Elektrischer Isolator, pyrolytische Bornitrid-PBN-Platte
Derzeit, conventional insulation materials have disadvantages such as low temperature resistance, Aluminiumnitrid 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. Hohe Reinheit, 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, Säure, 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.
PBN Heater Plate Applications:
For vacuum, Aluminiumnitrid, MBE equipment and other fields of insulation gasket, gasket, support, etc.
