What you don't know about silicon metal power
Silicon metal powder exhibits a dark gray color and has very good resistance, which is used in many industries. Metallic silicon, also known as crystalline silicon or industrially produced silicon, is used as a preservative for non-ferrous alloys.
Silicon metal is made of quartz stone and coke in the electric heater smelter into the commodity, the main ingredient of silicon element in the composition of 98 percent, the other residue for iron, aluminum, calcium and so on. The classification of metallic silicon is generally based on the composition of the three key residues, iron, aluminum and calcium, contained in the metallic silicon.
Silicon metal powder
In the organic silicon chemical manufacturing industry, silicon metal powder of belonging and a kind of organic silicon polymer material to generate the basic raw materials, such as use in manufacturing silicon single, silicone oil and silicone rubber additives, can with lifting goods heat-resistant properties and electrical characteristics of the dielectric strength and corrosion resistance, silicon metal powder as a kind of iron base preservatives, silicon steel alloy agent, can improve the steel cutting performance.
Silicon metal powder is mainly used in industrial production of refractory heat preservation material, also have of powder metallurgy, the characteristics of heat resistance and abrasion resistance is used to promote goods, also have the effect of oxidation resistance, industrial silicon powder production has made the single crystal silicon, silicon wafer production and processing of key is used in the new technology industry, is integrated circuit chips and electronic components can not be lack of raw materials.
Silicon metal powder melting point of silicon at one thousand four hundred ℃, melting point three hundred and fifty-five ℃ in two thousand yuan, if the silicon metal powder is filled in the gap of words, can increase bulk density, and reduce the porosity, and the compressive strength of goods also has significant improvement, water imbibition and specificity is also very good, is able to enhance the cohesion of the refractory insulation materials.
The metal silicon powder needle also has the very good improvement to their high temperature characteristic, increases the fireproof product's service life, uses in the converter, the industry kiln stove, the kiln fittings.
