1998-6-9 · Preferred polytypes for colorless silicon carbide gemstones are 6H and 4H SiC. The seed for initiating growth of the single crystal for such gemstones is the seed having the same polytype, 6H or 4H SiC respectively. To create crystals of hexagonal silicon carbide having different colors, one must intentionally add specific impurity atoms.
The properties of silicon carbide are highly dependent on its crystal structure (it can exist in many polytypes), on the quality of the crystal, and on the nuer and types of defects present. Manufacturers of silicon carbide raw material and devices need to monitor and control these attributes to enhance yield.
