Titanium diboride powder

Titanium diboride powder is gray or dark gray, with a hexagonal (AlB2) crystal structure. Its melting point is 2980℃, and it has very high hardness. Titanium diboride is oxidation-resistant in air up to 1000℃ and is stable in HCl and HF acids. The density can reach 4.52g/cm³; the coefficient of thermal expansion is 8.1×10-6m/m.k; the thermal conductivity is 25J/m.s.k; the resistivity is 14.4μΩ.cm; titanium diboride is mainly used to prepare composite ceramic products. Due to its resistance to molten metal corrosion, it can be used in the manufacturing of molten metal crucibles and electrolytic cell electrodes. 
Component structure: Titanium boride (TiB2) is the most stable compound of boron and titanium, with a C32-type structure, combined in its valence bond form, belonging to a hexagonal system of metalloid compounds. The structural parameters of its complete crystal are: a is 0.3028nm, and C is 0.3228nm. Boron and titanium atomic planes appear alternately in the crystal structure to form a two-dimensional network structure, in which B is covalently bonded to 3 other B atoms, and the extra electron forms a large bond. This graphite-like layered structure of boron atoms and the outer electrons of Ti determine the good conductivity and metallic luster of TiB2, while the Ti-B bonds between the boron and titanium atomic planes determine the high hardness and brittleness of this material.
