Thermal insulating material BN6000

electricboron nitridefor insulating systems

Overview
BN6000 is a hot-pressed hexagonal boron nitride (hBN) material developed for demanding industrial and aerospace environments. It offers high purity and improved mechanical performance compared with standard pure BN grades, while retaining stable behavior in plasma, vacuum and high-temperature inert atmospheres.

Technical characteristics

• Composition: hexagonal boron nitride (hBN)
• Maximum service temperature: 850°C in air; up to 2000°C in inert atmospheres
• Density: 2.0 g/cm3
• Flexural strength (RT): 52 MPa (parallel) / 60 MPa (perpendicular)
• Compressive strength: 40 MPa (parallel) / 60 MPa (perpendicular)
• Coefficient of thermal expansion (20°C–1000°C): 1.1 ×10^-6 (parallel) / 0.5 ×10^-6 (perpendicular)
• Thermal conductivity: ~21 W/m·K (anisotropic: ~21 parallel / ~21 perpendicular)
• Dielectric strength: >70 kV/mm
• Volume resistivity: ~1e14 ohm·cm

Product features
