Use	Chromium boride (CrB2) due to its excellent wear resistance, corrosion resistance, and high temperature oxidation resistance, hard tool materials and wear-resistant parts have a very broad application prospects. They are used as wear-resistant, high-temperature oxidation-resistant coatings and neutron-absorbing coatings in nuclear reactors. Used for ceramic, melt blown on the surface of metal and ceramic, forming a wear-resistant, corrosion-resistant film. For the spraying of semiconductor films. The products of Chromium boride and alumina sintered or hot-pressed in micro-oxidizing atmosphere have practical value of high temperature wear resistance. Used for ceramic, melt blown on the surface of metal and ceramic, forming a wear-resistant, corrosion-resistant film. For the spraying of semiconductor films.
production method	chromium and appropriate boron powder are heated at 1600 ℃ or sintered at 1150 ℃ for 48~72h in vacuum or inert atmosphere, chromium borides CrB, Cr2B, Cr3B2, Cr3B4 and CrB2 are formed, and CrB2, CrB or Cr3B4 can be formed after hot pressing at high temperature.
