High Thermal Conductivity Spherical Aluminum Nitride Powder is an advanced ceramic thermal conductive filler material mainly composed of aluminum nitride (AlN), produced through high-purity synthesis and spheroidization processes. The material combines excellent thermal conductivity, electrical insulation performance, low dielectric constant, low thermal expansion coefficient, and strong chemical stability, making it an important functional filler for thermal management applications in electronic packaging materials, thermal interface materials, heat-dissipation composites, copper-clad laminates, semiconductor packages, and power electronics. Compared with conventional aluminum nitride powders, spherical aluminum nitride powder provides higher packing density, improved flowability, reduced resin viscosity impact, and more uniform thermal conduction pathways, enabling higher filler loading and lower thermal resistance in composite materials. The product is typically manufactured through carbothermal reduction nitridation, direct nitridation, or plasma spheroidization technologies, with performance optimized through control of particle size distribution, sphericity, oxygen content, purity level, and impurity concentration to meet the requirements of high-performance electronic and semiconductor applications.
