■ Introduction:
Boron nitride conductive ceramic evaporation boat is a kind of container for high temperature evaporation and chemical vapor deposition (CVD) process. Boron nitride ceramics have the characteristics of high melting point, high hardness, high wear resistance and chemical stability, so they have excellent performance in the harsh environment such as high temperature, high pressure, strong acid and alkali.
