What is Boron Nitride (BN) Micron Powder?

Boron Nitride (BN) Micron Powder is a high-performance ceramic material known for its excellent thermal conductivity, electrical insulation, lubricating properties, and chemical resistance. Due to its hexagonal (h-BN), cubic (c-BN), and amorphous structures, BN powder is widely used in thermal management, electronics, lubricants, coatings, and high-temperature applications.
