Hexagonal Boron Nitride (h-BN): High-Performance Thermal & Electrical Insulation Material For Industrial Applications
Mar 21, 2026
Hexagonal boron nitride (h-BN) is a high-performance ceramic material widely used in vacuum coating, metallurgy, electronics, and high-temperature industries. Known as "white graphite," it offers a unique combination of thermal conductivity, electrical insulation, and chemical stability.
If you are facing issues such as material failure at high temperatures, metal adhesion, or poor heat dissipation, h-BN provides a proven and cost-effective solution.
What is Hexagonal Boron Nitride (h-BN)?
Hexagonal boron nitride is a synthetic advanced ceramic composed of boron and nitrogen atoms in a layered hexagonal structure. While structurally similar to graphite, it differs significantly in performance.
Key Advantage Over Graphite
1.Graphite: Conducts electricity
2.h-BN: Electrically insulating + thermally conductive
This makes h-BN ideal for applications requiring heat transfer without electrical conductivity.
