The substance was then named moissanite. After much research and development, synthetic moissanite (synthetic silicon carbide) was able to be grown into large crystals for jewelry appliions. Before that, silicon carbide was used for decades as an industrial abrasive (and still is).
What Is The Difference Between Alpha SiC And Beta SiC …
The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.

Moissanite from a real meteor | PriceScope Forum
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). The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life.

Moissanite Facts – DECENT GEMS MOISSANITE
Moissanite was discovered by a Nobel Laureate in Chemistry, Henry Moissan, back in 1893. Its composition is made of naturally occurring Silicon Carbide and was initially mistaken as a diamond. Eventually, he was able to correctly identify the gemstone named after him, studying the microscopic particles, created in the meteorite crater in Arizona.
