Product Description
The silicon component is mainly silicon, so it has similar properties to silicon. Silicon metal has two allotropes: amorphous silicon and crystalline silicon. Amorphous silicon is a gray-black powder and is actually a microcrystal. Crystalline silicon has the crystal structure and semiconductor properties of diamond, melting point 1410℃, boiling point 2355℃, Mohs hardness 7, brittle. Amorphous silicification is active and can burn violently in oxygen. It reacts with non-metals such as halogens, nitrogen and carbon at high temperatures, and can also interact with metals such as magnesium, calcium and iron to generate silicides. Amorphous silicon is almost insoluble in all inorganic and organic acids, including hydrofluoric acid, but soluble in mixed acids of nitric acid and hydrofluoric acid.
