Titanium diboride (TiB 2) is an extremely hard ceramic which has excellent heat conductivity, oxidation stability and wear resistance. TiB 2 is also a reasonable electrical conductor, [ 1 ] so it can be used as a cathode material in aluminium smelting and can be shaped by electrical discharge machining .
Hafnium diboride belongs to the class of ultra-high temperature ceramics, a type of refractory ceramic composed of hafnium and boron. It has a melting temperature of about 3250 °C. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and zirconium ...
Diboride may refer to: Aluminium diboride, compound of aluminium and boron; Hafnium diboride, ultra-high temperature ceramic composed of hafnium and boron; Magnesium diboride, inexpensive and simple superconductor; Rhenium diboride, synthetic superhard material; Titanium diboride, extremely hard ceramic compound composed of titanium and boron
Titanium diboride is a popular material for handling molten aluminum due to its electrical conductivity, refractory properties, and its ability to wet with molten aluminum providing a superior electrical interface while not contaminating the aluminum with boron or titanium.
