Habi has been inquiring from many aspects these days. In Germany, the strongest place in high-pressure sealed containers and chemical synthesis is at the Berlin University of Technology. The chemical engineering department here is also the most powerful place in the German chemical industry. Many of them shocked the world's chemical achievements, such as urea, vulcanized rubber, and some petrochemical achievements, which are directly related to this place. Currently, the annual chemical science awards also include German, European, and even some American chemical awards, which are often won here.

If Yang Yuanzhao was there, he would definitely instruct Habi again, the inventor of the famous Haber method of synthetic ammonia, Fritz Haber, discovered and improved the technology of synthetic ammonia at the Berlin University of Technology, and creatively synthesized ammonia from the air.

As a top university in Germany, the overall strength of science and engineering is firmly ranked among the top three in Germany, and the chemical engineering discipline is unique. This university has a strong foundation, and the chemical engineering department is even more so. When entering the campus, you can’t see students playing and playing. Most of the German students are in a hurry, and you can even see students working hard at any time on the lounge chairs on the side of the road.

According to the information he had inquired before, Habi looked for the building of the Chemical Engineering Department and found the deputy director of the Chemical Engineering Department, Professor Hoff, who was a Jew. Before coming to Berlin Polytechnic University, he contacted him through the Jewish Federation. Hoff was waiting in the office, and the time they agreed was 3 o'clock.

When he agreed to meet Professor Hoff, he was like an old friend. After chatting for a few words, Hoffbi told his purpose straight to the point. The high-pressure closed container was also one of the equipment that Yang Yuanzhao had added to the list before he set off.

At the beginning, he didn't care. After asking, Habi found out that high-pressure closed containers are definitely not an ordinary thing, this is a new topic.

It must bear huge pressure. Yang Yuanzhao's data can work smoothly under 70 atmospheres, which is quite OK. Some highly dense sealed cylinders can achieve such an effect, but the subsequent conditions make ordinary sealed containers unusable. This container needs to withstand the temperature that can withstand above 600 degrees.

The impact of high temperature on metal materials is far above high pressure. Under high pressure and high temperature conditions, the properties of metals will undergo great changes. Under low temperature and low pressure conditions, the properties of metals are stable and can be obtained by measuring methods. At higher temperatures, many metals with excellent performance will experience varying degrees of attenuation or even aging. In this case, it is very critical to obtain reliable metals, and this is also the only way to solve this container.

After hearing Habi's request, Hoff couldn't help frowning. High-pressure airtight containers still need to work at a temperature of about 600 degrees. This is a field that the School of Chemical Engineering has never been exposed to. Just as he was about to refuse, Hoff suddenly seemed to remember. There was a young lecturer in the Department of Chemical Engineering who seemed to be doing research in this area and seemed to have achieved results.

"Habbi, I don't know much about this field, but I will invite an expert for you. If he can't solve this problem, there is really nothing I can do!"

"Then Professor Raohoff!" said Habi.

He used a combo and called a teacher. After a few simple explanations, the teacher went out and came back soon. Following him was a middle-aged man with slightly bald hair and obvious Jewish characteristics.

"Mr. Hoff, come to me!"

"It's not me who is looking for you, it's this gentleman who is looking for you. He is a big businessman. I have a topic that you want to help you complete!"

Hoff's introduction made the middle-aged man's eyes lit up, and he warmly greeted him and said, "Hello sir, I am Fritz-Harber!"

During this period, Habi has met many senior officials, and even well-known scholars have seen them. He would not know that this is one of the most famous chemists in Germany in the future and is also a well-known figure. He won the Nobel Prize in Chemistry in 1918 because of his synthetic ammonia. He also produced a large amount of chlorine, mustard gas and other poison gases during World War I. Millions of people died because of him, so he was criticized by the academic community.

Now Harber is just an ordinary chemist. His idol is Li Bixi, who invented urea and is known as an agricultural industrialist. His current experiments are exactly the purpose of Yang Yuanzhao in making high-pressure closed containers. He synthesizes ammonia in the air, opening a new era of chemical engineering, and also gives Germany, which is under embargo, the confidence to start a war during World War II, because synthesizing ammonia is the only raw material for making nitric acid in addition to natural saltpeter.

Haber's enthusiasm made Haber a little at a loss. Hof next to him introduced: "Hab is the most familiar expert in our college, who is easy to be sealed in high temperatures. You can have a good chat!"

After Hoff said that, he went out and left the office to Harbor. In Hoff's brief introduction, Harbor understood that the other party's purpose was to high-pressure closed containers.

High-pressure closed containers are a new topic. It is strange to know that some people also need high-pressure closed containers. They also encountered enthusiasts or researchers of synthetic ammonia. In view of the identity of the big boss, Harber is willing to say a few more words. You should know that the experiment he has conducted recently has reached a critical step, and the funds are somewhat unable to keep up. He was able to reach this point. Thanks to the sponsorship of the two companies, his progress cannot satisfy the two companies. The funds have begun to delay, and the person in charge has also begun to become elusive, which makes him very troubled.

"I don't know what specifications you want!"

Hubi honestly said it according to Yang Yuanzhao's standards and said, "70 atmospheres, 600 degrees of high temperature, the volume must be large!"

Huber frowned and said, "With such high requirements, what exactly do you want to do, industrial production, scientific experiments?"

Habbi knew so much. Hab asked again, but he didn't know what to do. Hab had thought that high-pressure closed containers might have really met his peers. Researching in a field is like moving forward on a dark road. Habbi is better than constantly hitting walls.

After seeing Habi, it was not the case at all. He knew only a little about synthetic ammonia, but only made it according to the design standards. At most, it was just said that it should be as large as possible. This condition was much higher than synthetic ammonia. At this time, Habi discovered the method of synthetic ammonia, but he had not even completed industrial production. It was just a laboratory research. Even the catalyst completed this process at 20 atmospheric pressure and around 500 degrees. He was still in a intensive experiment to solve all problems and put this technology into real industrial production.

Haber is indeed professional. He has a relatively good understanding of high-temperature and high-pressure containers. Soon, according to Habi's requirements, calculated some data, and then through comparison and consideration, he said solemnly: "The maximum can be only 90 cubic meters. After accurate design, it will even be less!"

90 cubic meters, Hubby frowned and asked with a little inquiry: "Will it be too small!"

"It's not small, 90 cubic meters can synthesize liquid raw materials at least 100 tons at a time!" Haber said weakly. He was sure that Habi is a novice in chemistry and only has a slight understanding of chemical synthesis. However, he is really rich and does not consider any economical and affordable issues. He is considering performance indicators. The larger the high-pressure airtight container, the greater the pressure on the wall of the container. This is common knowledge that everyone knows in the metallurgical and chemical circles. Although 90 cubic meters is less than twice as high as 50 cubic meters, the price is at least four times. His experiment has reached a bottleneck. The key is that money is turbulent. There are not enough experiments and no better high-pressure airtight container. His synthesis of ammonia is successful, but it is still stuck.

Habi looked at Haber. He had one advantage, that was, he could listen to the professionals' narratives, and after repeated inquiries, he knew that he could not improve, so he agreed, ensuring that it was above 90 cubic meters as much as possible, and the minimum could not be lower than 80 cubic meters. For this reason, he could directly advance the entire amount.

Huber's eyes lit up. This was a high-pressure closed container, which was a creative move. Therefore, he also called for a higher price. A 50 cubic container was only 80,000 marks, and more than 80 cubic meters. He called for a high price of 500,000. In his opinion, it would be at least a big discount. 350,000 was his psychological price. However, he did not expect that with a wave of his hand, he ordered it, ordered three at one time, and left 1.5 million marks directly for the Department of Chemical Engineering of Berlin University of Technology.

Haber agreed in a hurry, just telling Habi that this type of high-pressure sealed container is extremely difficult to produce and takes 3 months.

"It will take 3 months!" Hubby frowned and asked, "Can you be faster!"

"No, this needs to be customized. In order to increase strength, the materials need to be used in a 10,000-ton water press. That is a national important weapon. Even if there is a brand of Berlin University of Technology, it will have to wait for a month or a month at most!"

When he heard about the 10,000-ton hydraulic press, Habi stopped talking. This is a real national weapon. Even in Germany, there are only the main shafts of warships, propellers, important components of the engine, as well as heavy artillery, naval guns, etc. You can pass it on a 10,000-ton hydraulic press and take this high-pressure airtight container to a 10,000-ton hydraulic press. I am afraid it is still for the money.

Seeing that Hubby stopped talking, Hubby quickly made a series of guarantees, such as carefully making this high-pressure airtight container, which would add some small but very useful parts. These parts were some of his achievements in the experiment and had a considerable effect on the sealing of the airtight container.

In short, after doing his best, Hubby finally left with satisfaction. Of course, before leaving, he put down a check of 1.5 million marks and left it directly to the Institute of Chemical Engineering as the funds for the production of three airtight containers.
