Laboratory Melting Crucible Made of BN Boron Nitride Ceramic

At present, conventional insulation materials have disadvantages such as low temperature resistance, low purity, gas release at high temperature, poor toughness, no insulation at high temperature, and easy to be corrosed. PBN insulation board can solve these problems. Name: high temperature resistant BN gold melting crucibles Borons Ceramic Main Features: 1. The maximum tolerance is 2300℃ in vacuum and 2700℃ in ammonia atmosphere; 2. High purity, high temperature does not release gas impurities (>99.99%); 3. Good toughness (hexagonal structure similar to graphite); 4. High temperature insulation (volume resistivity 3.11×1011 ω •cm); 5. Intensification of inert, acid, alkali, salt and organic solvent corrosion; 6. Low thermal conductivity in the DIRECTION of C can block the downward conduction of heat and reduce heat loss

Pyrolytic boron nitride is a grade of hexagonal boron nitride. It is produced by chemical vapor deposition process to create its solid body and all the boron nitride crystals grow parallel to the surface of which the vapor is deposited on. Due to the nature of CVD process, PBN parts generally are requested the wall thickness not more than 3mm. PBN is also a good choice for extremely high purity of boron nitride. 99.99% is the typical grade. The CVD process give this pyrolytic boron nitride almost perfect layered structure, which leads to nisotropic thermal conductivity, making it an ideal material to make crucibles for crystal growing. PBN Ceramic Applications： -Crystal growth (VGF, LEC Crucible) -Molecular Beam Epitaxy(MBE) Crucible -MOCVD Heater -PBN Infrared Window -Traveling Wave Tube (TWT) (PBN Support Rod) -PBN Coating Graphite -High temperature, vacuum equipment insulator
