Green Silicon Calcium Powder

Calcium and silicon have a strong affinity with oxygen. Especially calcium, not only has a strong affinity with oxygen but also has a strong affinity with sulfur and nitrogen. Therefore, silicon-calcium alloy is an ideal composite glue and desulfurized.

Silicon carbide has black silicon carbide and green silicon carbide two common varieties of the base, both belong to α-SiC. ① black silicon carbide contains about 95% SiC, its toughness is higher than green silicon carbide, mostly used for processing low tensile strength materials, such as glass, ceramics, stone, refractory materials, cast iron, and non-ferrous metals, etc.. ②Green silicon carbide contains about 97% SiC or more, good self-sharpening, mostly used for processing cemented carbide, titanium alloy, and optical glass, also used for honing cylinder liners and fine grinding high-speed steel tools. In addition, there is cubic silicon carbide, which is a special process to produce yellow-green crystals, used to make abrasives suitable for bearing ultra-fine machining, can make the surface roughness from Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 microns.

Black silicon carbide is a non-metallic mineral product generated from quartz sand and anthracite or petroleum coke as the basic raw material under high-temperature conditions above 1800 degrees Celsius and is an important raw material widely used in metallurgical deoxidation, production of refractory products, electronics, machinery, mold manufacturing, and other industries. Silicon carbide (sic) deoxidizer is a new type of strong composite deoxidizer, replacing the traditional silicon powder toner for deoxidation, and the original process compared to the physical and chemical properties of more stable, good deoxidation effect, so that the deoxidation time is shortened, into slag early, the reduction atmosphere is thick, saving energy, improve steelmaking efficiency, improve quality, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve labor conditions, improve the comprehensive electric furnace economic benefits of the furnace are of great value. In addition in the refractory bricks, water spout, electronic panels, etc., refractory material class is widely used
