Aluminum nitride powder for surface modification

Aluminum nitride powder has poor stability and can hydrolyze in water at room temperature, resulting in a decrease in the powder’s thermal conductivity. We offer a range of modified aluminum nitride powders tailored to various applications. Choose the appropriate modification based on your needs: silane modification for improved resin compatibility or hydrolysis-resistant treatment for enhanced moisture resistance.

Surface modification solutions with aluminum nitride powder

Tailor your aluminum nitride powder with specialized surface treatments to achieve optimal performance:

  • Silane coupling agent modification : Improves dispersion and bonding in polymer matrices (e.g., epoxy, silicone) for superior compound performance.
  • Inorganic Hydrolysis-resistant treatment : Provides long-term stability in humid or aqueous environments by preventing degradation from moisture.
  • Dual modification (Silane + Hydrolysis resistance) : Combines greater resin compatibility with environmental protection for demanding applications.

Surface modification of aluminum nitride. Powder hydrolysis tests.

Unmodified NAI undergoes almost complete hydrolysis after 2 hours at 70°C, resulting in a strong, irritating ammonia odor and the formation of clumps at the bottom of the container. In contrast, our modified product shows no ammonia odor or clumping even after 72 hours of hydrolysis, with virtually no signs of further hydrolysis.

  • Experimental conditions: 30g of Aluminum Nitride, 300g of pure water, water temperature at 70°C.
  • Experimental method: The degree of hydrolysis is determined by observing the experimental phenomena and measuring the pH of the solution.

We carry a wide variety of boron nitride products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

  • Improves compatibility with resins/polymers (reduces agglomeration).
  • They inhibit hydrolysis reactions (preventing the formation of Al(OH)₃ when exposed to air).
  • Optimize powder dispersion in the matrix (ensuring a more uniform thermal conductivity network).
  • Silane coupling agents (KH-550/KH-560): For epoxy resin/silicone rubber compounds.
  • Titanate treatment: Suitable for metal-based thermal conductive materials.
