![]() Wide-scale production is credited to Edward Goodrich Acheson in 1891. Albert Colson's heating of silicon under a stream of ethylene (1882).Paul Schuetzenberger's heating of a mixture of silicon and silica in a graphite crucible (1881). ![]() Robert Sydney Marsden's dissolution of silica in molten silver in a graphite crucible (1881).César-Mansuète Despretz's passing an electric current through a carbon rod embedded in sand (1849).Non-systematic, less-recognized and often unverified syntheses of silicon carbide include: Analysis of SiC grains found in the Murchison meteorite, a carbonaceous chondrite meteorite, has revealed anomalous isotopic ratios of carbon and silicon, indicating that these grains originated outside the solar system. ![]() The silicon carbide found in space and in meteorites is almost exclusively the beta-polymorph. It is a common form of stardust found around carbon-rich stars, and examples of this stardust have been found in pristine condition in primitive (unaltered) meteorites. While rare on Earth, silicon carbide is remarkably common in space. Moissan's discovery of naturally occurring SiC was initially disputed because his sample may have been contaminated by silicon carbide saw blades that were already on the market at that time. Ferdinand Henri Moissan, after whom the material was named in 1905. Natural moissanite was first found in 1893 as a small component of the Canyon Diablo meteorite in Arizona by Dr. Virtually all the silicon carbide sold in the world, including moissanite jewels, is synthetic. Naturally occurring moissanite is found in only minute quantities in certain types of meteorite, corundum deposits, and kimberlite. Moissanite single crystal (≈1 mm in size)
