Crucibles
- All kinds of crucible shapes
- Wide range of crucible sizes
- Standard PBN crucibles
- Refractory and noble metal crucibles (W, Ta, Ir, etc.)
- Pyrolytic graphite (PG) crucibles
- Al2O3, BeO and MgO crucibles
Pyrolytic boron nitride (PBN) crucibles have become the accepted crucible material for use in MBE growth of semiconductor materials because of the material's high purity, chemical inertness, thermal stability, low outgassing, non-wetting characteristics and long lifetime.
PBN can be used for temperatures up to 1500°C. The maximum temperature decreases with rising chamber pressure.
For higher temperatures or for special applications crucibles made of other materials like tungsten (W), tantalum (Ta), pyrolytic graphite (PG), silicon dioxide (quartz), aluminum oxide (Al2O3), beryllium oxide (BeO), or magnesium oxide (MgO).
Other crucible materials are available on request.
