Aluminum nitride nanopowder is a high purity, ultra-fine ceramic material with outstanding thermal conductivity, high electrical insulation, and excellent compatibility with advanced material systems. With particle sizes in the nanometer range, it offers a large specific surface area and high reactivity, making it ideal for use in next-generation thermal interface materials, electronic substrates, and composite enhancement.
Our AlN nanopowder is typically ≥99% pure and has uniform particle distribution, low oxygen content, and excellent dispersibility. We also offer comprehensive after-sales support—please feel free to contact us if you have any questions.
