Product Description
High quality ceramic pbn pyrolytic boron nitride part and plate


LEC PBN Crucible

1. Extremly High Purity

2. High Temperature

3. Excellent Thermal Shock Resistance

4. Chemical Inertness


Product Description


Pyrolytic Boron Nitride (PBN) is opaque white, non-toxic, non-porous, electrically insulating, easily machined, with very good resistance to thermal shock. Our Pyrolytic Boron Nitride crucibles (PBN crucibles) are always manufactured to our customer's specific requirements on shape and size, we do not stock any crucibles. The maximum size of our pyrolytic boron nitride crucibles (PBN crucibles) we can manufacture is diameter 330mm x height 500mm x 1.0mm wall thickness. Lead times are generally 4-6 weeks from receipt of official order. All crucibles are fully cleaned before packaging and shipping.

In addition to Pyrolytic Boron Nitride crucibles (PBN crucibles) we can also produce PBN tubes, PBN plate (max 4mm thick) and PBN components.
