TB-HBN-MCHexagonal Boron Nitride (h-BN) Ceramics
Hot-pressed hexagonal boron nitride (h-BN) crucibles, rods, plates, and precision CNC components combining extreme thermal shock resistance, molten-metal non-wetting, and electrical insulation.
Electrically conductive hot-pressed titanium diboride (TiB2, CAS 12045-63-5) plates and composite TiB2-BN-AlN resistive evaporation boats for continuous aluminum web/batch PVD and molten metal contact.
Titanium diboride (TiB2) is an ultra-hard refractory boride (MP ~3,225 °C, hardness ~2,800–3,200 HV) that conducts electricity like a metal (~9–15 µΩ·cm) and is completely wetted by—yet chemically resistant to—molten aluminum and cryolite.
We supply both monolithic hot-pressed TiB2 plates/crucibles (which can be shaped by wire-EDM!) and hot-pressed composite TiB2–BN–AlN intermetallic evaporation boats engineered for continuous wire-fed and batch thermal evaporation of aluminum.
