TITANIUM DIBORIDE

Titanium diboride (chemical formula TiB2) is an extremely hard ceramic compound composed of titanium and boron which has excellent resistance to mechanical erosion. TiB2 is also a reasonable electrical conductor, an unusual property for a ceramic, so it can be used as a cathode material in aluminium smelting and can be shaped by electrical discharge machining.TiB2 does not occur naturally in the earth.Titanium diboride powder can be prepared by a variety of high-temperature methods, such as the direct reactions of titanium or its oxides/hydrides. 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.
