CG MATERIAL

Boron Nitride Plate, BN Plate

Boron Nitride Plate, BN Plate

Boron Nitride Plate, also known as BN Plate, is a high-performance ceramic plate made from boron nitride (BN) powder. It is a white, highly crystalline material with a hexagonal lattice structure that gives it exceptional thermal and mechanical properties.

BN Plates are produced using a hot-pressing process that involves applying heat and pressure to BN powder, resulting in a highly dense, uniform material with excellent strength and thermal conductivity.

BN Plates are highly valued for their unique combination of properties, which include high thermal conductivity, excellent electrical insulation, low coefficient of friction, and resistance to thermal shock. These properties make BN Plates ideal for use in high-temperature applications, such as furnace linings, crucibles, and heat exchangers.

BN Plates are also highly resistant to chemical attack and can withstand harsh chemical environments, making them an ideal material for use in chemical processing and semiconductor manufacturing.

BN Plates are available in various thicknesses, ranging from thin sheets to thick blocks, and can be customized to meet specific application requirements. They are also available in a range of sizes and shapes, including rectangular, circular, and custom shapes.
