Silicon carbide /Sic structure
Products Information
Naturally occurring moissanite is found in only minute quantities in certain types of meteorite and in corundum deposits and kimberlite. Virtually all the silicon carbide sold in the world, including moissanite jewels, issynthetic. Natural moissanite was first found in 1893 as a small component of the Canyon Diablo meteorite inArizona by Dr. Ferdinand Henri Moissan, after whom the material was named in 1905. Moissan's discovery of naturally occurring SiC was initially disputed because his sample may have been contaminated by silicon carbidesaw blades that were already on the market at that time.
While rare on Earth, silicon carbide is remarkably common in space. It is a common form of stardust found aroundcarbon-rich stars, and examples of this stardust have been found in pristine condition in primitive (unaltered) meteorites. The silicon carbide found in space and in meteorites is almost exclusively the beta-polymorph. Analysis of SiC grains found in the Murchison meteorite, a carbonaceous chondrite meteorite, has revealed anomalous isotopic ratios of carbon and silicon, indicating an origin from outside the solar system; 99% of these SiC grains originate around carbon-rich asymptotic giant branch stars.
Products Aplication
1. Because of its high hardness, silicon carbide can be used as abrasive to make abrasive tools, such as grinding wheel, bistrique, abrasive stone etc.
2. Silicon carbide can be used as deoxidizer in the steelmaking. Using silicon carbide can shorten the time of deoxidizing, improve the quality of steel and alleviate the environmental pollution.
3. Sand blasting is made of Silicon carbide and other materials.
4. Silicon carbide can be used as semiconductor.
