Silicon metal powder is made of Silicon lumps by crushing, seiving, washing process etc.
We have different grades of Si content powder, and we have different Si powder crushing and sieving processes to adapt to different applications of silicon powder.
Normal size: 180 mesh -325 mesh, 200 mesh, 325 mesh, 800 mesh, etc.
Packing & Delivery
Packing: 1 ton big bag, 20-25mt in 20' container
The additional products of silicon metal include silicon micropowder, edge-skinned silicon, black-skinned silicon, silicon metal slag and so on. Among them, silicon micropowder, also known as silicon powder, microsilicon powder or silicon ash, is widely used in the refractory and concrete industries.
Industrially, silicon metal is usually produced by reducing silicon dioxide from carbon in an electric furnace. Chemical reaction equation: SiO2 + 2C → Si + 2CO The purity of silicon thus produced is 97~98%, called silicon metal. Then it will melt and recrystallize, with acid to remove impurities, to get the purity of 99.7 ~ 99.8% of the silicon metal. Silicon metal is mainly composed of silicon, so it has similar properties to silicon. Silicon has two kinds of isotopes: amorphous silicon and crystalline silicon. Amorphous silicon is a gray-black powder, which is actually a kind of microcrystal.
Crystalline silicon with diamond crystal structure and semiconductor properties, melting point 1410 ℃, boiling point 2355 ℃, Mohs hardness 7, brittle. Amorphous silicon is chemically active, in oxygen can burn violently. It reacts with halogens, nitrogen, carbon and other non-metals at high temperatures, but also with magnesium, calcium, iron and other metals to generate silicides. Amorphous silicon is almost insoluble in all inorganic and organic acids, including hydrofluoric acid, but is soluble in a mixture of nitric and hydrofluoric acids. Concentrated sodium hydroxide solution can dissolve amorphous silicon, releasing hydrogen gas. Crystalline silicon is relatively inactive, even at high temperatures, but not with oxygen, it is also insoluble in any kind of inorganic and organic acids, but can be dissolved in nitric acid and hydrofluoric acid mixture of acids and concentrated sodium hydroxide solution.
