Pyrolytic boron nitride is an advanced ceramic produced by chemical vapor deposition (CVD) process.
DMCERA® Pyrolytic Boron Nitride
Pyrolytic boron nitride is an advanced ceramic produced by chemical vapor deposition (CVD) process. Compared with normal boron nitride material, it has much better purity level and advantages. It is an ideal material for high temperature furnace,electrical components and compound semiconductor crystal growing. PBN ceramic can be easily machined into ceramic crucible, ceramic boat, ceramic plate, ceramic tube and other ceramic parts. PBN pyrolytic boron nitride components are widely used in aviation, aerospace, electronics, chemical industry, special metallurgy, and medical fields.
Advantages:
● Non-toxic and non-wetting
● High purity(＞99.99%).
● Easy to process
● Good thermal conductivity.
● Excellent thermal shock resistance.
● Max working temperature 2200℃
● Non-reactive to most other compounds.
Key Applications:
● PBN Rod
● OLED Crucible
● MOCVD Heater
● PBN coating graphite
● MBE,VGF,LEC Crucibles
● High temperature furnace insulator
