Alpha alumina is melted and processed into spherical shape by high temperature flame, and then screened and purified to obtain the finished product. The spherical alumina obtained is characterized by high purity, high spheroidization rate and controllable particle size distribution. This product has excellent characteristics such as high thermal conductivity, good fluidity and low oil absorption value.
