With the continuous development and innovation of science and technology, new equipment and new technologies have been applied in many industry fields.This improvement made up for the shortcomings of many devices that could not be used because some factors could not meet customer needs, so many emerging products and devices came out.The same is true in pressure vessel equipment. The materials used are also very different due to different uses. In addition to the common ones we have, there are also some special materials that are also popular for pressure vessel equipment.
For example, the polycrystalline silicon pressure vessels produced by our company have attracted much attention.Many people don’t know what polycrystalline silicon is. In fact, it is a form of simple silicon.When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged in the form of a diamond lattice to form many crystal nuclei. If these crystal nuclei grow into crystal grains with different crystal plane orientations, these crystal grains combine to form polycrystalline silicon. .It is soluble in mixed acid of hydrofluoric acid and nitric acid, but insoluble in water, nitric acid and hydrochloric acid.The hardness is between germanium and quartz. It is brittle at room temperature and easily broken when cut.It becomes ductile when heated to above 800℃, and shows obvious deformation at 1300℃.It is inactive at room temperature and reacts with oxygen, nitrogen, sulfur, etc. at high temperatures.In the high-temperature molten state, it has greater chemical activity and can interact with almost any material.Especially in the electronic industry, such as refrigerators, color TVs, video recorders and other products, it plays a great role.It can be seen that polycrystalline silicon pressure vessels are also very high-quality container equipment.
