In the field of thermal conductive composites, the selection of fillers is crucial. While metal and carbon fillers possess high thermal conductivity, high loadings can damage the material's insulation properties. Furthermore, carbon materials such as graphene and carbon nanotubes are difficult to disperse in the matrix, hindering the formation of effective thermal conductive pathways. In contrast, ceramic fillers, with their excellent heat transfer performance and high insulation properties, are an ideal choice for preparing high thermal conductivity composites. Among them, aluminum oxide fillers have attracted significant attention and widespread application due to their high thermal conductivity, high resistivity, low dielectric loss, and good cost-effectiveness. Spherical aluminum oxide fillers can better utilize the heat conduction function of the thermal conductive filler.。
Currently, there are various methods for preparing spherical aluminum oxide powders, including homogeneous precipitation and sol-gel methods.-emulsion-gel methods. Ball milling, as a common process for preparing ultrafine aluminum oxide powders, usually utilizes a honeycomb millto carry outthe conversion ofpowder. Thisequipment
has significant advantages in preparing spherical alumina, including simple operation, low cost, and high output.The homogeneous precipitation method has mild process conditions, and the spherical aluminum oxide powder produced has high sphericity, with an average particle size distribution of10400 nanometers to
micrometers, and excellent dispersion properties. This method also uses honeycomb milling equipment. After initial mixing and surface modification, it undergoes cleaning, drying, dispersion, and high-temperature calcination to finally obtain spherical aluminum oxide powder.Honeycomb millisacontinuous productionmultifunctional equipment, integratingpowder spheronization, surface modification,depolymerization,and dryingmultiple functions, and can perform a series of processes such as dry grinding, powder surface modification, spheronization, and drying. Its unique mechanochemical modification technology can effectively improve the surface properties of the powder, providing strong technical support for the preparation of spherical aluminum oxide powder. With its efficient, energy-saving, and environmentally friendly features, honeycomb millsare widely used in large-scale industrial productionspherical aluminum powder
