Pyrolytic Boron Nitride Ceramic Crucible Pbn Bn with Ring Boat Rod Plates
Application
Boron nitride ceramics can be used in the manufacture of high-temperature containers for metallurgical melting, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells, and glass forming dies.
Product Description
Boron nitride crystal belongs to the hexagonal crystal system, its structure is similar to that of graphite, and its performance has many similarities, so it is also called "white graphite". Boron nitride is a crystal composed of a nitrogen atom and a boron atom. The chemical composition is 43.6% boron and 56.4% nitrogen with four different variants: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) and wurtzite nitrogen. Boron (WBN).
