BN crucible

 

high purity PBN crucible

High purity PBN crucible, PBN (Pyrolytic Boron Nitride) crucible for LEC (liquid encapsulant czochralski) crystal growth (MADE IN CHINA)

Airy Technolog Co., Ltd. offer high purity PBN crucible made in China.

 

Introduction
PBN is a special ceramic material, made by CVD(Chemical Vapor Deposition) with special equipment. PBN is deposited on a graphite substrate at a temperature over 1800 centidegreeand under a pressure of less than 10 Torr. Process of sedimentation is like “snow”: PBN hexagonal snowflake,fall on the graphite base material in parallel. After reaching certain thickness and cooling, it will be molding through ingot stripping.

Characteristic
1. Product color is between ivory white and orange-brown, nontoxic, imporosity, easy processing.
2. The purity is up to 99.99%, surface densification, good gas barrier properties.
3. The strength increases as temperature rises and peaked at 2200℃,heat-resistanc.
4. Acid, alkali, salt and organic reagent resistant. Meanwhile ,it do not react with the majority of moltenmental and semiconductor material.
5. Excellent thermal shock resistance, excellent thermal conductivity, low thermal expansion coefficient.
6. High resistance, high dielectric strength, low dielectric constant, low dissipation factor, excellent microwave and infrared ray ability.
7. It has obvious anisotropy in the mechanics, heat and electricity.
