Molecular beam epitaxy (MBE) is one of the most important III-V and II-VI semiconductor crystal epitaxial growth processes in the world today. PBN crucible is the best container for evaporating elements and compounds in MBE process.
The crucible for OLED is used as the evaporation element container in the OLED production line
Product description
Pyrolytic boron nitride is a kind of boron nitride prepared by chemical vapor deposition through high temperature pyrolysis reaction. When it comes to boron nitride, we must first talk about the two main structures of boron nitride: hexagonal and cubic. This is very similar to the two crystal forms of carbon: graphite and diamond. Hexagonal boron nitride and graphite are very similar in many respects, hence the name white graphite for hexagonal boron nitride. Pyrolytic boron nitride is hexagonal boron nitride, but strictly speaking, it has a certain amount of turbostratic structure. The main feature of PBN prepared by chemical vapor deposition is that its purity is very high, which can reach more than 99.99%.
