OLED熱分解窒化ホウ素穴付きセラミックパイプ
Pyrolytic Boron nitride PBN ceramic：
OLED crucible is a PBN crucible used in OLED and CIGS evaporation technology. With its ultra-high purity, 化学的不活性, excellent high temperature resistance and high temperature stability, it is widely used in metal and semiconductor evaporation.
Boron nitride ceramic is chemically and has relatively good thermal conductivity, low thermal expansion and microwave clarity. Boron nitride can be quickly machined as well. Moreover, glass, salts and the rest of liquid metals are non-wetting. This ensures that neither of these compounds can be moistened, and it is far more immune to chemical assaults.六方晶窒化ホウ素 (h-BN) performs very well under high heat condition and is effective in the air at temperatures of up to 900 degrees C, in the vacuum at 1,900 degrees C and in the inert environment at 2,000 degrees C. BN is self-lubricating as well,したがって、より長い寿命を保証します, it does not need the use of molecules of gas or water stuck in its layers. Because of this, in a vacuum, which is important for aerospace applications, boron nitride (BN) can work perfectly.
