AlN Powder Surface Modification Methods
You can choose the appropriate aluminum nitride powder modification based on your specific needs. For example, if you require improved compatibility with resins, select silane modification; for enhanced moisture resistance, opt for hydrolysis-resistant treatment.
- Silane Coupling Agent Modification: Enhances compatibility with specific matrix systems such as silicone or organic resins.
- Inorganic Hydrolysis Resistance Treatment: Improves resistance to hydrolysis, allowing for better stability in humid environments.
- Inorganic Hydrolysis Resistance + Silane Coupling Agent Modification: Combines hydrolysis resistance with silane treatment for enhanced performance in different application systems.
AlN Powder with Inorganic Hydrolysis-Resistant Modification
AlN is widely used in electronics for its high thermal conductivity (320 W/(m·K)), but it reacts with water after moisture absorption, reducing its thermal performance. Surface treatment with coupling agents can lower its hydrolysis but limits further treatment. HM's inorganic coating method overcomes this, allowing further organic coatings and providing better stability for high-reliability applications.
