Zirconium Boride Usage And Synthesis
  • Chemical PropertiesGray metallic crystals or powders. Mohs hardness 8, electrical resistivity 9.2 micro-ohm-cm (20C), excellent thermal shock resistance, poor oxidation resistance above 1100C.
  • UsesRefractory for aircraft and rocket applications, thermocouple protection tubes, high temperature electrical conductor, cutting tool component, coating tantalum, cathode in high-temperature electrochemical systems.
  • Industrial usesZirconium boride is a microcrystalline graypowder of the composition ZrB2. When compressedand sintered to a specific gravity ofabout 5.3, it has a Rockwell A hardness of 90,a melting point of 2980°C, and a tensilestrength of 241 to 276 MPa. It is resistant tonitric and hydrochloric acids, to molten aluminumand silicon, and to oxidation. At 1204°Cit has a transverse rupture strength of 379 MPa.It is used for crucibles and for rocket nozzles.
