Boron Nitride Ceramic Disc High Purity Thermal Insulator Up to 2000°C

What is a Boron Nitride Ceramic Disc

A boron nitride ceramic disc is a precision-engineered component made primarily from boron nitride (BN), a unique material known for its exceptional thermal, electrical, and chemical properties. These discs serve a variety of industrial applications requiring high-temperature resistance, electrical insulation, and chemical inertness.

There are two main types of boron nitride ceramic discs based on their manufacturing process and structure:

• Hot-Pressed Hexagonal Boron Nitride (hBN) Discs: Produced by applying heat and pressure to boron nitride powders, hot-pressed hBN discs offer excellent thermal conductivity, mechanical strength, and machinability. Their hexagonal crystalline structure enables superior thermal shock resistance and electrical insulation.
• Pyrolytic Boron Nitride (PBN) Discs: Made by chemical vapor deposition, PBN discs feature a highly oriented crystal structure. This gives them outstanding purity, higher density, and superior dielectric strength, making them ideal for high-performance vacuum and semiconductor environments.

Gotrays specializes in supplying high-purity boron nitride discs that meet stringent quality and performance standards. With advanced manufacturing techniques and rigorous quality control, Gotrays provides both hBN and PBN discs tailored to demanding industrial applications. Their expertise ensures products that deliver consistent, reliable performance in critical processes.
