Product Description
This product is high-purity electronic-grade spherical aluminum oxide powder, specifically optimized for thermal interface materials (TIM). It features high thermal conductivity, low thermal resistance, and excellent insulation properties. Prepared by a high-temperature melt-spraying method, the particles exhibit high sphericity (≥95%) and uniform particle size distribution (D50 2-50μm adjustable), significantly enhancing the heat dissipation efficiency of thermal interface materials such as thermal grease, thermal pads, and phase-change materials.
