Overview
Detailed PhotosThe classification of silicon metal is usually classified according to the content of iron, aluminum and calcium contained in the silicon metal components. According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into 553 441 411 421 3303 3305 2202 2502 1501 1101 and other different brands.
In industry, silicon metal is usually made by carbon reduction of silicon dioxide in the electric furnace chemical reaction equation: SiO2 + 2C Si + 2CO so that the purity of silicon metal is 97~98%, called silicon metal and then melt it after recrystallization, with acid to remove impurities, the purity of silicon metal is 99.7~99.8%
Silicon metal is mainly composed of silicon, so silicon has similar properties with amorphous silicon and crystalline silicon two allotrope amorphous silicon is gray black powder, in fact, is also a kind of microcrystalline silicon with diamond crystal structure and semiconductor properties, melting point 1410, boiling point 2355, Mohs hardness 7, brittle.
Amorphous silicon has active properties and can be burned violently in oxygen. It can react with nonmetals such as halogen nitrogen and carbon at high temperature, and can also react with metals such as magnesium, calcium and iron to form silicides. Amorphous silicon is almost insoluble in all inorganic and organic acids. Concentrated sodium hydroxide solution can dissolve amorphous silicon, hydrogen crystal silicon is relatively inactive, even at high temperature does not combine with oxygen, it is insoluble in any kind of inorganic acid and organic acid, but soluble in concentrated sodium hydroxide solution
Our products are produced on the basis of best technical team, advanced equipment, high qualified management which meet the requirements of security and environmental protection. We earned customer trust and created a good reputation during these years.
We will provide the most comprehensive products and service to you ! We are looking forward to your cooperation!
