Product Description

Introduction of Boron Nitride Crucible

---

 

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.

 

 

Product name :high temperature resistant gold melting crucibles Boron 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

 

 

PBN Plate Applications:

 

For vacuum, high temperature, MBE equipment and other fields of insulation gasket, gasket, support, etc.
