Titanium Boride

Titanium Boride (TiB2) is an extremely hard ceramic which has excellent heat conductivity Boron Product, oxidation stability and wear resistance. Titanium Boride Powder is also a reasonable electrical conductor,so it can be used as a cathode material in aluminium smelting and can be shaped by electrical discharge machining.With respect to chemical stability, TiB2 is more stable in contact with pure iron than tungsten carbide or silicon nitride.

Titanium Boron Diboride is resistant to oxidation in air at temperatures up to 1100 °C,and to hydrochloric and hydrofluoric acids, but reacts with alkalis, nitric acid and sulfuric acid.

Current use of Titanium Boron Powder appears to be limited to specialized Boric Acid Flakes applications in such areas as impact resistant armor, cutting tools, crucibles, neutron absorbers and wear resistant coatings.

TiB2 is extensively used for evaporation boats for vapour coating of Melamine Powder aluminium. It is an attractive material for the aluminium industry as an inoculant to refine the grain size when casting aluminium alloys, because of its wettability by and low solubility in molten aluminium and good electrical conductivity.

Thin films of TiB2 can be used to provide wear and corrosion resistance to a cheap and/or tough substrate.
