DOMADIA™ Hexagonal Boron Nitride (hBN) Powder

Introduction

Domadia™ proudly presents Hexagonal Boron Nitride (hBN) Powder, an advanced ceramic material known as “White Graphite”. With a hexagonal layered structure, hBN offers a unique combination of thermal conductivity, chemical inertness, electrical insulation, and lubricity—making it a multi-functional solution for various demanding industrial and scientific applications.

About the Product

Hexagonal Boron Nitride (hBN) is a white, scaly crystalline powder consisting of boron and nitrogen atoms arranged in a hexagonal lattice. Domadia™ offers high-purity hBN in particle sizes ranging from 70 nm to 30 microns, allowing precision-tailored performance for industries such as aerospace, electronics, metallurgy, optics, and cosmetics.

Key Features

1. Structure: hBN is structurally similar to graphite, with layered boron and nitrogen atoms arranged in a hexagonal lattice.

2. Thermal Conductivity: Efficient in heat dissipation, ideal for electronics and high-performance thermal management systems.

3. Chemical Inertness: Resistant to acids, bases, and molten metals, enabling durability in corrosive environments.

4. Electrical Insulation: Functions as a wide-bandgap semiconductor with excellent dielectric strength.

5. Mechanical Strength: High load-bearing capability makes it durable for structural and high-pressure applications.

6. Lubricity: Low friction coefficient due to weak van der Waals forces between layers—effective for high-temp dry lubricants.

7. Thermal Stability: Maintains structural integrity and performance up to 1800°C in inert gas, 1400°C in vacuum, and 1000°C in air.

8. Light-Matter Coupling: Ideal for deep ultraviolet (DUV) optoelectronics, sensors, and advanced photonic applications.

Key Technical Properties

Applications 

1. Parts: manufacture of crucibles, boats, molten metal carriage pipes pumps, thermocouple protection sheaths and lining of reaction vessels.

2. Thermal Management: Used in heat-dissipating components and polymer composites for electronics.

3. Electrical Insulation: Serves as a filler for insulating materials, substrates for semiconductors, and barrier layers in electronics.

4. High-Temperature Lubrication: Dispersed in oils, greases, or dry form for efficient high-temp lubrication.

5. Corrosion Protection: Coatings for crucibles, pipes, thermocouple sheaths, and vessels exposed to molten metals.

6. Mold Release Agent: Ideal for metal, plastic, titanium, and glass molds—improves product surface finish and extends mold life.

7. Glass Manufacturing: Applied as a non-wetting protective coating for forming and processing glass.

8. Aerospace and Defense: Used in high-temp parts, launch vehicles, thermal shields, and insulation layers.

9. Cosmetics and Specialty: Adds silky texture, spreadability, and glow in skincare and makeup formulations.

10. Optoelectronics: Suitable for DUV emitters, photodetectors, and integrated photonic circuits due to strong light-matter interactions.

11. Advanced Composites: Integrated into ceramics, rubbers, resins, and alloys to enhance thermal and mechanical performance.

12. Memerane Technology: h-BN membranes are used for filtration and separation processes, including wastewater treatment and hydrogen/deuterium separation.
