Vitreous carbon

Syn.: Glass-like carbon, glassy carbon

Vitreous carbon  a non-graphitizing, or nongraphitizable, carbon which combines glassy and ceramic properties with those of graphite. The most important properties are high temperature resistance, hardness, low density, low electrical resistance, low friction, low thermal resistance, extreme resistance to chemical attack and impermeability to gases and liquids.
Glassy carbon is used as a component of some prosthetic devices, and can be fabricated as different shapes, sizes and sections. It was used in the 1970 as dental implant.
