Boron nitride (BN) is a high-performance engineering ceramic material distinguished by high heat resistance, poor wettability by many melts, and very good electrical insulating properties. Thanks to its combination of thermal, chemical, and electrical characteristics, boron nitride is used in various demanding industrial and technical fields.
The material combines good thermal conductivity with low electrical conductivity, making it particularly suitable for applications where efficient heat dissipation is required while maintaining electrical insulation. Boron nitride also features good chemical resistance, heat resistance, and resistance to thermal shock.
Boron nitride is used in engineering ceramics, high-temperature materials, crucibles and molds for working with molten metals, as well as a release and coating material. In addition, it is in demand in the electronics and semiconductor industries.
