Technical Description of titanium diboride powder

Nano titanium diboride powder and ultrafine titanium diboride powder were prepared by the gas phase method of variable current laser ion beam, with high purity, small particle size, uniform distribution, large specific surface area and high surface activity. Ultrafine titanium diboride ceramic powder is a kind of gray black powder, and the powder particles have a complete hexagonal crystal structure.  Its chemical formula is TiB2, molecular weight 69.52, density 4.52 g/cm3, melting point 2980℃, microhardness 34Gpa, thermal conductivity 25J/ M.S.K, thermal expansion coefficient 8.1×10-6m/ m.K, electrical resistivity 14.4μ ω.cm.  Titanium diboride powder has high melting point, high hardness, wear resistance, acid and alkali resistance, excellent electrical conductivity, strong thermal conductivity, good chemical stability and thermal vibration resistance, high oxidation resistance temperature, can resist oxidation below 1100℃, its products have high strength and toughness.  

Application of titanium diboride powder

Titanium diboride powder is one of the main raw materials of vacuum coating conductive evaporation boat, composite ceramic material.  It can be used as an important component of multiple composite materials, and TiC, TiN, SiC and other materials to form composite materials, making various high temperature resistant parts and functional parts, such as high temperature crucible, engine parts and so on.  It is also one of the good materials for making armor protection materials, ceramic cutting tools and molds.  Can manufacture finishing tools, drawing die, extrusion die, sandblasting nozzle, sealing elements, etc.  Cathode coating material for aluminum electrolytic cell.  Because of the good wettability between TiB2 and liquid aluminum, using TiB2 as cathodic coating material can reduce the power consumption of aluminum electrolytic cell and prolong its service life.  It is made into PTC heating ceramic material and flexible PTC material, which is energy-saving, reliable and easy to process and form, etc. It is a high-tech product updating all kinds of heating materials.  Conductive ceramic materials.
