     Intermetallic crucibles are composed of 50% Titanium Boride (TiB2) and 50% Boron Nitride (BN). Its density is 2.77 g/cc, with a thermal expansion coefficient (CTE) of 7 (in/in/°Cx10-6) and thermal conductivity of 70 (W/m°K)/25°C. The material is both lubricious and electrically conductive. The crucible is both strong and conductive, yet its lubricious properties prevent material spill-over and crucible cracking.
