MOISSANITE (Silicon Carbide)

Moissanite is a mineral that was first discovered in fragments of the meteorite at Diablo Canyon or Meteor Crater in Arizona. It was named in honor of its discoverer, Nobel Prize winner Dr. Ferdinand Henri Moissan. Synthetic moissanite is also known as silicon carbide after its chemistry and by the trade name, carborundum.In the meteoritic material, moissanite is associated with tiny diamonds.

Large Synthetic Moissanite with Silicon Carbide Polytypes

Silicon carbide (SiC) is composed of a carbon atom surrounded by four silicon atoms in a tetrahedral form. Colorless synthetic moissanite is pure silicon carbide; the incorporation of impurities produces colors, including black. Its high hardness (second only to diamond) and thermal conductivity make it a convincing diamond simulant.

Machining of Silicon Carbide - Process, Appliions and Types

There is also chemical vapor deposited silicon carbide called CVD Silicon Carbide, which is an extremely pure form of the compound. To sinter the Silicon Carbide its is necessary to add sintering aids which help to form a liquid phase at the sintering temperature which allows the grains of silicon carbide to bond together.
