Boron nitride (BN) nanopowder is an advanced material with a set of unique features that make it highly sought after in various high-performance applications. Its structure is similar to graphite, with layers of hexagonal networks, which can also be transformed into cubic and other polymorphs at the nanoscale, each with distinct properties,BN nanopowder exhibits excellent thermal conductivity, especially in its hexagonal form, making it ideal for use in thermal management applications where efficient heat dissipation is required.Despite its high thermal conductivity, BN is an excellent electrical insulator, providing unique opportunities for its use in electronics where thermal management is critical without affecting the electrical properties.It remains stable at temperatures up to 1000°C in air and up to 2800°C in inert atmospheres, making it suitable for high-temperature applications.Similar to graphite, hexagonal BN (h-BN) can act as a dry lubricant due to its layered structure, which allows the planes to slide over each other easily.

BN nanopowder is used in electronic substrates, insulators, and encapsulants. It’s particularly valuable in high-power electronic devices for heat dissipation without electrical interference.
In applications requiring efficient heat dissipation, such as LED lighting, power electronics, and processors, BN nanopowder is incorporated into thermal interface materials (TIMs) to enhance thermal conductivity and manage device temperatures.
BN nanopowder is used in coatings to improve surface properties such as resistance to wear, corrosion, and thermal shock. These coatings are applicable in aerospace, automotive, and chemical processing equipment.
The lubricious nature of hexagonal boron nitride (h-BN) makes it suitable for use as a dry lubricant in applications where liquid lubricants would be unsuitable, such as in high-temperature or vacuum environments.
Due to its soft feel, good adhesion, and optical properties, BN nanopowder is used in cosmetic formulations as a bulking and oil-absorbing agent, providing a smooth and silky texture to makeup products.
In ceramics, BN nanopowder contributes to improved thermal shock resistance, thermal conductivity, and mechanical properties, making these ceramics suitable for high-performance applications.
