titanium boride usage:
Current use of TiB2 appears to be limited to specialized applications in such areas as impact resistant armor, cutting tools, crucibles and wear resistant coatings.
TiB2 is extensively used as evaporation boats for vapour coating of 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 for wear and corrosion resistance that TiB2 can provide to a cheap and/or tough substrate.
