It is 100 times stronger than bulletproof glass . The United States uses it to make the best bulletproof glass. The United States defines transparent aluminum as "one of the most important defense materials in the 21st century". Is the method becoming transparent really so strong? How far has China's transparent aluminum developed? Will the United States get stuck in the neck in the future? Hello everyone, with these questions, let's walk into today's cold knowledge class of popular science, pay attention and don't get lost
What is transparent aluminum?
Everyone has heard very little about transparent aluminum, because it is not yet popular, the biggest reason is that the price is too expensive, more than 10 US dollars per square inch, this material once appeared in the sci-fi movie " Star Trek ", but In reality, military transparent aluminum can even withstand the attack of transparent bullets, and its visible strength is stronger than bulletproof glass.
The production method of transparent aluminum is to first make a model, and pour the powder of aluminum nitride oxide into a fixed mold to form a fixed shape , and then through the hydraulic mode, the powder is compressed into green granules, and then heated by high temperature at 2000 degrees, and finally the finished product is formed. ".
The hardness of transparent aluminum is very high, which is comparable to sapphire. It has a direct transmittance of more than 90% to visible light such as violet , infrared , etc., and the high temperature resistance exceeds 2000 degrees Celsius. The bulletproof ability of transparent aluminum is very good. It is related to the thickness. For the same thickness of transparent aluminum and bulletproof glass, the bulletproof ability of transparent aluminum is twice that of bulletproof glass.

Application of transparent aluminum
Transparent aluminum is mainly used in the military field. At present, the use of transparent aluminum in the United States is relatively large, mainly used in the production of bulletproof glass for combat armored vehicles , and transparent windows for missile sensors.Most of the applications in the military are reflected in the role of replacing transparent bulletproof glass. Although it is expensive and has not been popularized today, it has been looking for the possibility of commercial use. It may be seen in bulletproof automotive glass and computer electronic equipment parts in the future. The figure of transparent aluminum, and it is also possible to see transparent beverage cans on beverages.
The United States is higher than China in the research of transparent aluminum, and transparent aluminum has a great use in the military field, especially in high-end weapons and equipment. The protection and safety are much higher than other materials, but China will not is waiting , the development of transparent aluminum in China has entered the experimental stage. Scientists from the Shanghai Research Institute used urea formaldehyde test paper and alumina as raw materials, and successfully developed a method of making transparent aluminum through pressing and high temperature processes.
And light transmittance can also reach 80%, Shanghai FRP Research Institute has also produced transparent aluminum with light transmittance exceeding 87% by carbon reduction method after 24 hours of high temperature heating. There is very little news about transparent aluminum, and each country has not publicly stated it, but I believe that we will not be blocked by the United States because of this technology. If we want to become a world power , we must have our own core competitiveness , that is, self-created
, although there is a certain gap with the United States, but in the near future, it will definitely catch up or surpass. After reading the editor's sharing, everyone thinks that transparent aluminum will one day be made into a mobile phone screen? no longer has to worry about breaking the phone screen.
