Boron Nitride Ceramic Product

BN Boron Nitride Ceramic For Mechanical Seals / Aerospace Application

Description:

Boron nitride (BN) ceramics are advanced materials fabricated from hexagonal boron nitride (h-BN) powders through high-temperature sintering. With a theoretical temperature limit of 3000℃ and operational capability up to 2300℃ in inert gases, BN ceramics excel in thermal stability, thermal conductivity, high-temperature dielectric strength, and chemical inertness. They serve as ideal solutions for thermal management and high-temperature insulation in semiconductor, metallurgy, and aerospace applications.

Typical application:

1. Mechanical Seals: High-temperature bearings, valve rings (operating >1200℃)

2. Cutting Tools: Ceramic inserts (second only to diamond in hardness)

3. Electronics: Substrates for power modules (high thermal conductivity, insulation)

4. Aerospace: Engine combustors, radomes (lightweight, microwave transparency)

5. Chemical/Biomedical: Corrosion-resistant piping, artificial joints (biocompatible)
