Pyrolytic graphite coated PBN (pyrolytic boron nitride) crucible refers to a crucible made of PBN material with a coating of pyrolytic graphite on its surface. The purity of Pyrolytic Graphite Coated Crucible is over 99.99% and the air tightness is good, which has high-temperature resistance, chemical stability, good thermal shock resistance, good thermal conductivity, low coefficient of thermal expansion, resistance to acid, alkali, salt, and organic reagent corrosion. In addition, it has a long service life. Pyrolytic graphite coated PBN crucibles are commonly used in high-temperature applications, such as semiconductor manufacturing, crystal growth, metallurgical processes, and materials research, where both high thermal stability and chemical resistance are critical.
