Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.

how to extract a broke carbide drill bit? [Archive] - The

Never, EVER drill small holes with carbide drills unless the work is completely restrained and unable to move. Because if it moves evena tiny bit the carbide will shatter like glass. This means the work is in a vise and the bit is in a drill press or mill - not a hand drill! Carbide is for drilling tough materials not silver.

List of silicon producers - Wikipedia

This is a list of silicon producers.The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon.High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering.

Moissanite: The Second Hardest Mineral in Nature after Diamond

Mineral moissanite was discovered by Henri Moissan while examining rock samples from a meteor crater loed in Canyon Diablo, Arizona, in 1893. At first, he mistakenly identified the crystals as diamonds, but in 1904 he identified the crystals as silicon carbide. The mineral was named in his honour.
