What is Hexagonal Boron Nitride (h-BN) Powder Used For? | DOMADIA™
Introduction: The Silent Hero of High-Performance Materials
Every high-tech industry has its unsung hero. For electronics, aerospace, and lubrication systems — that hero is hexagonal boron nitride (h-BN). Known as the “white graphite,” this remarkable ceramic material is rewriting what we expect from performance powders.
At DOMADIA™, we specialize in providing premium-grade hexagonal boron nitride powder that delivers precision, purity, and consistency — engineered for industries where failure is not an option.
What Exactly Is Hexagonal Boron Nitride (h-BN)?
Hexagonal boron nitride (h-BN) is a ceramic compound made up of boron (B) and nitrogen (N) atoms arranged in a hexagonal lattice — structurally similar to graphite.
However, unlike graphite, h-BN is electrically insulating and thermally conductive, making it an ideal choice for applications that demand both heat resistance and electrical isolation.

Applications of Hexagonal Boron Nitride (h-BN) Powder
Hexagonal boron nitride (h-BN) powder is a truly versatile performer, widely recognized for its ability to withstand extreme conditions while maintaining exceptional thermal, electrical, and mechanical stability. Below are some of its most prominent industrial applications.

1. Thermal Management in Electronics
In the electronics industry, h-BN acts as a powerful heat spreader and thermal filler, ensuring efficient heat dissipation while maintaining complete electrical insulation. It’s widely used in semiconductor packaging, heat sinks, and PCB insulation layers, preventing overheating and extending the lifespan of sensitive electronic components — a must for high-performance devices.
2. Lubricants & Coatings
As a dry lubricant, h-BN offers unmatched performance in high-temperature or vacuum environments. It significantly reduces friction in forging dies, aerospace systems, and automotive components. Additionally, it serves as an excellent mould release coating for glass and metal casting, producing smoother finishes and enhancing tool durability.
3. Aerospace & Defense
h-BN’s thermal endurance and chemical inertness make it a critical material in aerospace and defense applications. It is commonly used in rocket nozzles, turbine blades, and thermal shields, where it helps components endure extreme heat and stress while minimizing maintenance downtime — ensuring reliability in demanding missions.
4. Metallurgy & Foundries
In metallurgical processes, h-BN works as a non-stick protective coating for crucibles, molds, and ladles. It prevents metal adhesion, improves surface finish, and prolongs equipment life. Its resistance to oxidation and corrosion ensures consistent performance even in extreme-temperature metal handling operations.
5. Cosmetics & Personal Care
High-purity cosmetic-grade h-BN provides a silky, luxurious texture in powders, foundations, and skincare products. Being non-toxic and chemically stable, it’s safe for the skin and delivers superior smoothness for premium formulations.
6. 3D Printing & Advanced Ceramics
In additive manufacturing and ceramics, h-BN enhances mechanical strength, wear resistance, and thermal stability. Its integration in 3D-printed composites makes it a cornerstone for next-generation engineered materials — where performance meets innovation.
