Hot pressing, pyrolysis boron nitride ceramic crucible with lid

Boron nitride ceramics are made of boron nitride powder after hot pressing and sintering into product blocks, and then processed according to the size specifications required by customers. According to the sintering method, it is generally divided into hot-pressed boron nitride and pyrolytic boron nitride.
Pyrolytic boron nitride (PBN) belongs to the hexagonal crystal system and is an advanced ceramic material with a roughness of 99.999%, acid and alkali resistance, oxidation resistance, good thermal conductivity, compactness and processability.
The main types are related, rods, sheets, rings, crucibles, nozzles, special-shaped parts, etc.
