Boron nitride (BN) is a crystal composed of nitrogen atoms and boron atoms, with a chemical composition of 43.6% boron and 56.4% nitrogen. It has a melting point of 2700°C, is insoluble in cold water, has a density of 2.29 g/cm³, and appears as white powder or translucent crystals.
Crystal structure
Boron nitride has four different variants: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN), and wurtzite boron nitride (WBN). The most common variant is hexagonal boron nitride, which has a structure similar to graphite, so it is also called "white graphite".
Application areas
Refractory materials: used for high-temperature furnaces, crucibles, etc.
Semiconductor materials: used for semiconductor solid-phase doping sources.
Radiation protection materials: used for packaging materials to protect against neutron radiation.
Lubricants: have good self-lubricating properties.
High-temperature insulation materials: used for high-temperature bearings, thermocouple sleeves, etc.
Cutting Tools: Cubic boron nitride is used to make drill bits, abrasives and cutting tools.
