Electrical Insulator Pyrolytic Boron Nitride PBN Plate

At present, conventional insulation materials have disadvantages such as low temperature resistance, قليل 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.

PBN Heater Plate Main Features:
1. The maximum tolerance is 2300℃ in vacuum and 2700℃ in ammonia atmosphere;
2. عالية النقاء, 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, إشعال سيراميك نيتريد السيليكون بدرجة حرارة عالية, قلوي, 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.

PBN Heater Plate Applications:

For vacuum, درجة حرارة عالية, MBE equipment and other fields of insulation gasket, gasket, support, إلخ.
