Moissanite, also known by its chemical name, silicon carbide (SiC), is a naturally occurring mineral found in very limited quantities or as minute particles in the earth. The rarity of natural moissanite crystals large enough for jewellery prohibits their use. For years, scientists tried to re-create this extraordinarily brilliant material.

Moissanite from a real meteor | PriceScope

16/5/2010· 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 (SiC).[2][3] The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life.

What Is The Hardness Of Silicon Carbide? - Ceramics

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600°C with no strength loss. . Gerry The Jeweler.

Source Silicon Carbide Experts for Projects, Phone …

Due to the rarity of natural moissanite, silicon carbide is typically man-made. Most often it is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600 and 2500 °C.
