Overview of Boron Nitride Ceramic

Boron Nitride (BN) ceramic is a unique material renowned for its exceptional properties, making it highly valuable in various industrial applications. It exists in multiple forms, primarily hexagonal boron nitride (h-BN), cubic boron nitride (c-BN), and wurtzite boron nitride (w-BN). Hexagonal BN, the most common form, is often compared to graphite due to its lubricious and thermally conductive yet electrically insulating nature. Boron Nitride ceramics are synthesized under high temperatures and pressures, offering a rare combination of properties not found in many other materials.
