Abstract

We report on the lowermost pressure and temperature conditions where cubic zirconium(IV) nitride having Th3P4-type structure, c-Zr3N4, forms in a belt-type apparatus. This novel hard material having exceptional wear resistance by machining of low-carbon steels appears at pressures between 6.5 and 7.7 GPa when heated to 1400-1600 degrees C. Single-phase samples were obtained at P = 7.7 GPa thus indicating that the industrial scale synthesis of this innovative material is feasible. Chemical reaction of the sample material with the Pt-capsule led to formation of a Pt Zr alloy, as a minor admixture, which can potentially be used as a binder for cementing of polycrystalline c-Zr3N4 tools.
