Silicon carbide, abbreviated as SIC. Darshan Alloy is a professional manufacturer of metallurgical silicon carbide in China. We have extensive experience in the field of steelmaking.
Types of silicon carbide: balck silicon carbide and green silicon carbide. Both are hexagonal crystals. The specific gravity is from 3.20 to 3.25. The microhardness is 2840 ～ 3320kg / mm2.
Black silicon carbide
The number of silicon carbide used in steelmaking is set to a new high every year. Its toughness is higher than that of green silicon carbide. Black silicon carbide contains about 95% SiC. This element can play a good application effect in steel making.

Silicon carbide manufacturing process
Quartz sand, petroleum coke (or coal coke), wood chips, etc. are used as raw materials. It is then smelted at high temperature through a resistance furnace.
Black silicon carbide uses
Black silicon carbide can effectively deal with oxygen in molten steel during steelmaking. The condition that oxides float on the surface of molten steel is beneficial to improve the purity of molten steel. On the other hand, the use of black silicon carbide in the deoxidation of steelmaking can reduce the chance of defects. For example, subcutaneous bubbles and looseness.
Green silicon carbide
The manufacturing method of green silicon carbide is the same as black silicon carbide. It's just that one more element added during smelting is table salt. However, the purity of raw materials used is relatively high.
It is formed at a high temperature of about 2200 ° C in a resistance furnace. The physical properties are similar to black silicon carbide. But the performance is slightly more brittle than black. Green silicon carbide has good thermal conductivity and semiconductor chracteristics.

Green Silicon Carbide Application
Green silicon carbide contains more than 97% of SiC. Its price is also higher than that of black silicon carbide. Mostly used for processing hard alloys, titanium alloys and optical glass.
