Boron Nitride (BN) is a unique ceramic material that offers an exceptional combination of thermal conductivity and electrical insulation, making it ideal for high-temperature, dielectric, and chemically aggressive environments. It is a preferred material in industries such as semiconductors, metallurgy, aerospace, and vacuum systems.
Boron Nitride is a non-oxide ceramic composed of boron and nitrogen, often available in hexagonal (hBN) or hot-pressed forms. It resembles graphite structurally but offers opposite properties: electrical insulation instead of conductivity, while retaining high thermal conductivity, chemical inertness, and machinability.
We offer CNC machining for high-purity sintered Boron Nitride (BN).
