Zirconium Carbide Powder (ZrC):


Zirconium Carbide Powder is insoluble in HCl but soluble in H2SO4. readily oxidized in air at elevated temperatures. Zirconium carbide (ZrC) is an extremely hard refractory ceramic material, commercially used in tool bits for cutting tools. It is usually processed by sintering. It has the appearance of a gray metallic powder with the cubic crystal structure. It is highly corrosion resistant.

Like most carbides of refractory metals, zirconium carbide is sub-stoichiometric, i.e., it contains carbon vacancies. At carbon contents higher than approximately ZrC0.98 the material contains free carbon.

ZrC reacts with water and acids and is pyrophoric.

Typical Applications:

  1. It is used as an abrasive, in metal cladding, in cermets, incandescent filaments and cutting tools.
  2. The mixture of zirconium carbide and tantalum carbide is an important cermet material.
  3. Hafnium-free zirconium carbide and niobium carbide can be used as refractory coatings in nuclear reactors. Zirconium carbide is used extensively as coating of uranium dioxide and thorium dioxide particles of nuclear fuel. The coating is usually deposited by thermal chemical vapor deposition in a fluidized bed reactor.
