physical properties of metal zirconium

The refractory diborides (HfB2 and ZrB2) are considered as promising ultra-high temperature ceramic (UHTCs) where low damage tolerance limits their application for the thermal protection system in re-entry vehicles.

ZrC is one of the potential materials for high temperature applications in hypersonic vehicles and weapons points like re-entry vehicle, rocket/Scram jet engine or supersonic vehicle.

The addition of zirconium silicide can increase the wear resistance and high temperature resistance of the material, carbon ceramic brake pads, and brake discs. The mass fraction of zirconium disilicide is 10-15%. Adding this mass fraction of zirconium disilicide into the ceramic matrix composite material can significantly reduce the sintering temperature of the material preparation.

Carbide ultra-high temperature ceramics mainly include zirconium carbide (ZrC), tantalum carbide (TaC) and hafnium carbide (HfC),

Zirconium carbide is used as a catalyst in a REDOX cell for the oxidation of chromous ions to chromic ions and for the reduction of chromic ions to chromous ions. The zirconium carbide is coated on an inert electronically conductive electrode which is present in the anode fluid of the cell.
