Chromium boride powder is a chemical compound with important chemical properties and its chemical formula is CrB. The preparation methods of chromium boride powder mainly include high temperature synthesis and molten salt electrolysis. High temperature synthesis method is under high temperature and high pressure, chromium and boron oxide or elemental reaction in the furnace, and then refined and purified to obtain chromium boride powder. Molten salt electrolysis is the use of molten salt electrolysis of chromium oxides or alloys to prepare chromium boride. Chromium boride powder has a wide range of applications. Due to its excellent wear resistance and high temperature stability, it is widely used in the preparation of high strength and high hardness ceramics and alloys. In addition, chromium boride powder can also be used to manufacture new battery materials and high-performance electronic devices.

Chromium boride can be used as wear-resistant, high-temperature oxidation resistant coatings and neutron absorption coatings in nuclear reactors. It can be used in ceramics and melt-blown on the surface of metals and ceramics to form wear-resistant and corrosion-resistant films. It can also be used to spray semiconductor films. Chromium boride and alumina are sintered or hot-pressed products in a slightly oxidizing atmosphere, which has the practical value of high temperature wear resistance.
