지르코늄카바이드

Zirconium carbide , nominally ZrC, is a dark gray brittle solid. It is made typically by a carbothermic reduction of zirconium oxide in a induction-heated vacuum furnace. Alternative production methods, especially for deposition on a substrate, consist of vapor-phase reaction of a volatile zirconium halide, usually ZrCl4, with a hydrocarbon in a hydrogen atmosphere at 900–1400 °C (1652–2552 °F).
