Introduction

Hexagonal boron nitride (hBN) powder is a versatile compound with a hexagonal crystalline structure similar to graphite. Known for its unique properties, hBN is utilized across various industries. Its applications are largely due to its excellent thermal conductivity, chemical stability, and lubricating properties.

Applications of hBN Powder

Lubrication

hBN powder serves as a superior lubricant due to its low coefficient of friction and chemical inertness. It functions optimally at temperatures up to 900°C in air and 1400°C in an inert atmosphere. This makes it ideal for high-temperature applications where traditional lubricants fail.

Ceramic Additives

In ceramic production, hBN powder is added to enhance the mechanical and thermal properties of the material. The ceramics exhibit improved thermal shock resistance and dielectric strength, making them suitable for use in high-performance environments.

Thermal Management

Due to its high thermal conductivity (ranging from 60 to 200 W/m·K), hBN is used in thermal management systems. It is incorporated into polymer composites, adhesives, and thermal pastes to dissipate heat effectively.

Cosmetic Industry

In cosmetics, hBN powder functions as a texturizing agent, providing a silky feel and enhancing product spreadability. Its chemically inert nature ensures compatibility with a broad range of formulations.

Electronics

hBN powder is used in the electronics industry for its excellent electrical insulation properties. It supports the manufacturing of substrates and insulating layers in semiconductor devices, operating efficiently at high temperatures without degrading.

Technical Specifications

hBN powder typically boasts a particle size in the range of 1-10 microns and a purity of 99% or higher. Its density is approximately 2.1 g/cm³, with a melting point of around 2973°C. The material exhibits a dielectric strength of about 56 kV/mm, making it an optimal choice for electrical insulation applications.
