Military Industry of Great Powers: Build the Strongest Flanker

At Mianzhou 452 Airport, a Yunqi took off from the airport, heading straight towards the Magic City. The news has been notified to the Magic City. At the 853 Airport in the Magic City, the entire site was on alert, with a battalion of soldiers escorting them. The military also Wheeled armored vehicles were brought in.

It was already late at night, and in the magic city of Hongkou, the lights of the 152 Research Institute of the Academy of Sciences were still on. The main materials experts were all present, and all of them looked unhappy and had mixed emotions.

"Research Institute 14 conquered gallium nitride crystal, did I hear that correctly?"

“I haven’t heard that they have any plans to develop a gallium nitride crystal project!”

"It would be great if it turns out to be a mistake!"

"Probably not. It's understandable that Institute 14 will make some jokes, but don't forget, Zhao Zhongshu is here too!"

"..."

Zhao Zhongshu is the leader in the technical field of C Fei. He was originally from S Fei. Ten years ago, S Fei split up and separated out a group of backbones who went to the southwest to establish C Fei.

In terms of technical talent alone, it was not inferior to S Fei at that time.

Lao Zhao also served as the director of Institute 258 of the Academy of Sciences.

Could it be a joke to follow such a person here?

"Perhaps, C Flying has not achieved anything impressive since its establishment. General Master Zhao is not doing it just for the limelight this time..."

No matter what level you are at, there will always be sarcastic remarks.

Liang Zhujin, a member of the Academy of Sciences, is over 60 years old. He studied in the West before the founding of the People's Republic of China and was immersed in the research of micromolecular chemistry.

At this time, he frowned slightly. To be honest, he didn't quite believe this information.

High-purity gallium nitride crystals are controlled in the West. The gallium nitride crystals flowing to major domestic universities are not pure enough, and their properties are naturally affected. Even so, the West sends people to take inventory at all times, just in case you use it. Other uses.

"It would be a good thing if it is really solved!"

It's not a pleasant feeling to have someone's neck choked.

By the time Zhao Zhongshu and his party rushed from the airport to the research institute, it was already midnight.

This did not affect the timing of the expert seminar at all, and the samples were quickly sent to the laboratory to be scanned under an electron microscope.

Zhao Zhongshu was crowded to the middle position, while Director Gao was at the lower left of General Master Zhao.

The people in front of them are Beidou, the Taishan of the Chinese scientific community.

No one spoke at the conference table, and the preliminary test results would be available in half an hour.

As for why I didn't start, I was afraid of making an own mistake. If the report was finished later and it turned out to be false, it would be a joke.

Director Gao turned his head to look at Chief Zhao and saw that he looked as usual, but he kept drinking water. In less than twenty minutes, the service staff had already refilled three glasses!

"It's been such a torturous time!"

The group of people in Research Institute 152 looked at them one by one, as if they were monkeys. Damn it, who could stare at people so directly!

I don’t know how long it took, but the people in the conference room opened with a creak.

Everyone's eyes were like radar, staring at the door. This pressure made the service staff who opened the door almost gasp.

Just when they were a little disappointed, a staff member wearing a laboratory uniform walked in behind them. He came directly to Commissioner Liang, handed him the report document in his hand, and said, "Teacher Liang, The test report is ready!”

"call!"

Everyone's breathing became a little heavy. Among them, Commander Wan Guozhong, who was sitting under Liang Zhujin, felt like he couldn't breathe.

Chief Wan is the deputy leader of the gallium nitride crystal research project team and has been working on it for three years.

Their work was not fruitless. The direction of his research was the metal polymer meteorological crystal deposition method.

Through the medium, crystal growth is carried out.

They can now create gallium nitride crystals with a thickness of one centimeter. However, unfortunately, due to the participation of media polymer compounds, although the deposited crystals can be formed in large blocks, they have too many impurities and the purity is only 100%. Ninety-nine point seventy-eight points, the physical properties are far worse.

You must know that the purity of gallium nitride wafers imported from the United States is also 99.9%. Even this purity is not enough. The excellent physical properties depend on how many nines are hung after the decimal point.

The purity of silicon crystals needs to be at least six nines before it can be used, while gallium nitride crystals also need to have three nines.

This is going to kill you.

How much work does it take to increase the purity by several orders of magnitude?

"Has it been created?"

"How pure is it?"

The experts from Institute 152 all looked at Liang Zhujin with eager eyes.

They are also entangled in their hearts. On the one hand, they hope that there will be a breakthrough, and at least the country will not be stuck on gallium nitride crystals. On the other hand, it is a hateful self-esteem.

Everyone in the business can solve this problem, but they, the professionals, have become just decorations.

After Liang Zhujin finished reading the report, he looked up at Zhao Zhongshu. When he saw Zhao Zhongshu put the tea cup on the table, he looked up at him.

"You should have guessed it earlier, right?"

Zhao Zhongshu smiled. The gallium nitride crystal in C Fei's laboratory has a purity of 99.9, and its appearance is not as good as the one made from 14. Although C Fei's equipment cannot detect the specific crystal phase and purity.

But in terms of material appearance and properties, the purity of 14 should be higher than that of the wafer imported from the West. As for how much higher, he couldn't say. With luck, it could be an order of magnitude higher, reaching ninety-nine point ninety-nine. That's not bad.

You must know that ultra-high purity gallium nitride crystal has three orders of magnitude, 99.999% purity, and three nines of purity. It is an absolute strategic material and is prohibited from export.

In fact, the material experts here are far beyond their reach, and the national goal is only to have a purity of one nine. They cannot imagine what kind of three-nine crystals the Western experts say exist. This technological gap is suffocating.

Zhao Zhongshu looked at his watch and said, "Let's announce it, everyone is sleepy."

"Haha! You!"

Liang Zhujin shook the report in his hand and said: "Under such difficult conditions, C Flying 14 successfully developed gallium nitride crystal. Its purity has reached two nines..."

"Huh! Two nines, that's right!" Everyone was breathing heavily, Zhao Zhongshu's face looked like it was true, and Dean Gao, he was numb. He was not a material expert, but from the looks of it, this The technology should be very impressive.

Liang Zhujin continued: "It should be accurate to three nines, the purity is 99.997%!"

"This is the Sanjiu Crystal!"

It's a pity, it's just a little closer to reaching Sanjiu purity.

The quality of 39% is the top level in the world. Their current purity of 997 can only be said to be the international advanced level. If it is not even close, it is a world of difference.

But at this time, it was something serious. The conference room was boiling. Everyone looked at Zhao Zhongshu like hungry wolves.
