Hexagonal Boron Nitride (h-BN) Powder – Advanced Ceramic Material With Exceptional Thermal & Lubrication Performance
Feb 24, 2026
Product Introduction
Hexagonal Boron Nitride (h-BN) powder is a high-performance inorganic non-metallic material with a layered crystal structure similar to graphite. Unlike graphite, however, h-BN combines excellent thermal conductivity with superior electrical insulation, making it a unique and versatile engineering material.
Our h-BN powder is produced under strict quality control to ensure high purity, consistent particle size distribution, and stable performance. It is suitable for a wide range of industrial and high-tech applications requiring thermal management, lubrication, chemical resistance, and electrical insulation.
Key Performance Characteristics
1. Excellent Thermal Conductivity
Hexagonal boron nitride exhibits high in-plane thermal conductivity, making it ideal for heat dissipation and thermal interface applications.
2. Superior Electrical Insulation
Unlike graphite, h-BN is electrically insulating while maintaining thermal conductivity, making it highly valuable in electronic and semiconductor applications.
3. Outstanding High-Temperature Resistance
①Stable in air up to approximately 900°C
②Stable in inert atmospheres above 2000°C
③Low thermal expansion and excellent thermal shock resistance
4. Exceptional Solid Lubrication
Its layered structure provides low friction and self-lubricating properties, even under high temperature and vacuum conditions.
5. Strong Chemical Stability
Resistant to most molten metals, acids, and alkalis, ensuring durability in harsh chemical environments.
6. High Purity & Customizable Specifications
Available in various particle sizes and purity levels to meet specific industrial requirements.
