What is the difference between silicon carbide and metal silicon


There are many types of silicon, and due to their different purity, particle size and chemical properties, they have different names and uses. Taking metal silicon as an example, metal silicon is often used in the field of smelting and can be used as a reducing agent for many metal smelting. So what is the difference between metal silicon and silicon carbide?

Silicon metal is a kind of silicon containing impurities. The impurities are iron, aluminum, and calcium. The content of silicon is 98%. High-purity metal silicon is semiconductor silicon. The chemical formula of silicon carbide is SiC, commonly known as emery, and has great hardness. High temperature resistance, wear resistance. It is a new type of ceramic.

Metal silicon is also called industrial silicon or crystalline silicon. Dark gray, with metallic luster, high melting point, good heat resistance, high resistivity, and high anti-oxidation effect; the general particle size is 10~100mm or 2~25mm; produced in submerged arc furnace internal reducing agent and silica smelting It is mainly used to formulate alloys, especially aluminum alloys, to prepare polysilicon and organic silicon and high-grade refractory materials.

Silicon carbide is a carbon:silicon crystalline compound produced by the reduction reaction of high-purity quartz sand and high-quality finely washed anthracite in a resistance furnace. It is characterized by stable chemical properties, high hardness and high temperature resistance. Because of its stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance, silicon carbide has many other uses besides abrasives.
