Product Description
This product is a high-purity aluminum oxide powder (Al2O3), specially developed for high-end electronic applications such as electronic ceramic substrates, circuit boards, and insulating devices. It features high purity, excellent sintering activity, and stable dielectric properties, ensuring high strength, high thermal conductivity, and superior insulation for ceramic substrates. It is suitable for harsh electronic environments such as high-frequency circuits, power modules, and LED packaging.
Core Advantages
High purity (≥99%) - Low sodium and potassium content to avoid electron migration issues
Optimized particle size distribution (2-50μm) - Balances sintering density and molding performance
High sintering activity - Reduces sintering temperature and energy consumption
Excellent dielectric properties - Suitable for high-frequency circuit applications
High thermal conductivity (20-30 W/m·K) - Improves heat dissipation efficiency of electronic devices
Strict quality control - Batch-to-batch stability within ±1%
