Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, can be produced with 99.999% purity in high density. It made by ammonia and Boron halide through Chemical Vapor deposition(CVD) process in high temperature and high vacuum condition:NH3 +BX3=BN+3HX , it can be produced as PBN plates, and also can be produced as PBN final products directly like crucible, boat, coating, etc.
2. Main Features
It's different from BN, there is no traditional process of hot pressing, no need any kinds of agglutinant, so the products have very obliviously features as follow:
- Non-toxic and tasteless
- High purity(>99.999%)
- No reaction with acid, alkali, salt and other organic reagent at room temperature
- A little corrode in melt salt and alkali, but it can resistance any kind of acid in high temperature.
- No reaction with melt metal, semiconductor and other compound.
- Excellent oxidation resistant below 1000ºC
- Excellent thermal shock resistance
- Can be used in high-temperature, no sublimation point, will be decompose into B&N
- High electrical resistance, good electrical insulating property
- Smooth surface, pore-free, not melt with most of semiconductor
- Crystal growth (VGF, LEC Crucible)
- Molecular Beam Epitaxy(MBE) Crucible
- Polycrystalline Synthesis Boat
- OLED and MBE Effusion Cell
- MOCVD Heater
- PBN Infrared Window
- Traveling Wave Tube (TWT) (PBN Support Rod)
- PBN Coating Graphite
- High temperature, vacuum equipment insulator
