Titanium Boride (TiB2)
Titanium Diboride is an extremely hard ceramic compound (34 GPa) composed of titanium and boron that has very good wear resistance. It is resistant to oxidation in air at temperatures up to 1000 °C, and to hydrochloric and hydrofluoricacids, but reacts with alkalis, nitric acid and sulphuric acid. Unusually for a ceramic, it is a reasonable electrical conductor (about 10E5 Siemens per centimetre), so can be used as an anode material in aluminium smelting; this also means it can be shaped by electrical discharge machining.
Applications,
1. Conductive polymers.
2. The tools and components for pottery and porcelain cutting.
3. Complex ceramic.
4. Cathode material for Aluminum electroanalysis.
5. Crucibles and wear resistant coatings.
6. It is also used as an inoculant to refine the grain size when casting aluminium alloys. |
