EUClass = not listedZirconium carbide (ZrC) is an extremely hard refractory
ceramic material [Measurement and theory of the hardness of transition- metal carbides , especially tantalum carbide. Schwab, G. M.; Krebs, A. Phys.-Chem. Inst., Univ. Muenchen, Munich, Fed. Rep. Ger. Planseeberichte fuer Pulvermetallurgie (1971), 19(2), 91-110] , commercially used intool bit s for cutting tools. It is usually processed bysintering . It has the appearance of a gray metallic powder with cubiccrystal structure . It is highlycorrosion resistant.Zirconium carbide reacts with water and acids and is
pyrophoric .Mixture of zirconium carbide and
tantalum carbide is an importantcermet material.Hafnium -free zirconium carbide andniobium carbide can be used as refractory coatings innuclear reactor s. Zirconium carbide is used extensively as coating ofuranium dioxide andthorium dioxide particles ofnuclear fuel . The coating is usually deposited by thermalchemical vapor deposition in a fluidized bed reactor.It is also used as an
abrasive , inmetal cladding , incermet s, incandescent filaments and cutting tools.References
