What is Spherical Al2O3 Powder? Specular alumina is a kind of alumina powder material obtained by irregular high-purity alumina calcination, high-temperature melting injection, screening, and purification. The product has high thermal conductivity, insulation, hardness, high-temperature, corrosion resistance, wear resistance, and other properties. It has good fluidity, low oil absorption value, high spherical rate, high α phase content, small specific surface area, controllable particle size distribution, and other unique and excellent characteristics.
Main uses of Spherical Al2O3 Powder Spherical alumina serves as a thermal interface material, For thermal conductive silicone inserts, thermally conductive silicone grease, thermal conductive sealing adhesive, thermal conductive double-sided adhesive, phase change materials, etc.; Also available as thermal conductivity engineering plastics, For LED lampshades, switch shells, electronic product shell, electrical product heat dissipation components (heat sink, filler for heat dissipation substrate, MC substrate), etc.; As a heat-conducting aluminum-based copper-clad plate, For high-power LED circuit base board, power supply circuit board, etc.; Using spherical alumina as a polishing abrasive can avoid creating scratches; In the petroleum chemistry industry, Increasing requirements for the pore size distribution and pore structure of the alumina carrier, The spherical alumina powder can regulate the pore size and its distribution of the formed catalyst carrier particles by adjusting the particle size configuration; The spherical alumina used directly as a catalyst can reduce wear, Improve the service life of the catalyst, Thus reducing production costs; The spherical oxide powder particles are sprayed on metals, plastic, etc., Can greatly improve the surface hardness, corrosion resistance, wear resistance and fire resistance, For the surface protection of machinery, cutting tools, and chemical pipelines; The spherical alumina powder has a high packing density, Can reduce the scattering of the light emission volume, Effectively reduce the loss of transmitted light, Thus improving the light transmittance; Due to the excellent characteristics of spherical alumina in terms of electrical, thermal and mechanical properties, It is very widely used in the field of semiconductor electronic packaging. Characteristics of spherical alumina With a high spherical rate and controllable particle size distribution, spherical alumina can fill silica gel and epoxy in high density to obtain a mixture with low viscosity and good liquidity. Due to its spherical appearance, spherical alumina can realize multi-direction of heat transfer, good dispersion in the system, and high thermal conductivity of conductive heat products; spherical alumina reduces the wear of mixer, forming machine, and other equipment and extends the life of the equipment.
