Reference Information about Zirconium Carbide (ZrC) Evaporation Material

ZrC is a important high temperature structure materials with high melting point, high strength and anti-corrosion. And it can absorb visible light, reflect infrared rays and store up energy efficiently. It also has anti high temperature, anti-oxidation, high strength, high hardness, good thermal conductivity, good toughness and so on..

strong covalent Zr-C bond gives this material a very high melting point (~3530 °C), high modulus (~440 GPa) and hardness (25 GPa). ZrC has a lower density (6.73 g/cm3) compared to other carbides like WC (15.8 g/cm3), TaC (14.5 g/cm3) or HfC (12.67 g/cm3). ZrC seems suitable for use in re-entry vehicles, rocket/scramjet engines or supersonic vehicles in which low densities and high temperatures load-bearing capabilities are crucial requirements.

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 is stable for a carbon-to-metal ratio ranging from 0.65 to 0.98.

The group IVA metal carbides, TiC, ZrC, and SiC are practically inert toward attack by strong aqueous acids (HCl) and strong aqueous bases (NaOH) even at 100' C, however, ZrC does react with HF.

The mixture of zirconium carbide and tantalum carbide is an important cermet material.

Hafnium-free zirconium carbide and niobium carbide can be used as refractory coatings in nuclear reactors. Because of a low neutron absorption cross-section and weak damage sensitivity under irradiation, it finds use as the 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. It also has high emissivity and high current capacity at elevated temperatures rendering it as a promising material for use in thermo-photovoltaic radiators and field emitter tips and arrays.

It is also used as an abrasive, in cladding, in cermets, incandescent filaments and cutting tools.
