What is Spherical Al2O3 Powder?
Spherical Al2O3 Powder has excellent mechanical properties and is often used as a grinding medium in various mills. Spherical Alumina has high compressive strength and wears resistance. Spherical al2o3 has high filling property, and its particles have a Spherical high rate and wide particle size distribution. It can fill rubber and plastic with high density to obtain a mixture with low viscosity and good fluidity.

Secondly, the spherical oxidation furnace also has high thermal conductivity. Because it can be filled with high density, compared with crystalline silicon powder, a mixture with high thermal conductivity and good heat dissipation can be obtained. Spherical alumina has the characteristics of high sphericity and high content of α-phase alumina, and it shows superior performance when used as a filler for rubber, plastics and ceramic raw materials.
The characteristics of spherical alumina
Spherical alumina powder has high sphericity, good fluidity, low powder surface energy, reasonable particle size distribution, good particle gradation relationship, and a considerable filling number. It is especially suitable for producing products with high thermal conductivity requirements. Its appearance is spherical, significantly reducing the wear and tear on the equipment, and it can be used for high-precision equipment and prolong the service life of the equipment. Spherical alumina can be widely used as a high thermal conductivity filler in various silica gel, epoxy resin, thermally conductive plastic, thermal conductive potting compound, rubber, ceramic raw materials, fine polishing and other fields.
Applications of Spherical Aluminum Oxide Al2O3 Powder
The spherical alumina powder has a large specific surface area, and the particle surface is rich in mismatched and oxygen-deficient bonds. It will contain large holes when pressed into thin sheets, with the hole ratio reaching 30-40%. It can be made into a porous membrane filter, and the performance of the catalyst and catalyst carrier made from it is several times superior to that of similar products currently in use. Nano-sized spherical alumina powder is extremely sensitive to humidity and has a high application value in temperature sensors. It can be widely used in semiconductor materials such as substrate materials of large-scale integrated circuits. Nano-spherical alumina powder can not only be used to synthesize new composite ceramic materials with unique properties but also be used to make composite materials such as artificial teeth and bones.
Spherical alumina powder particles sprayed on metals and plastics can significantly improve surface hardness, corrosion resistance, wear resistance and fire resistance and can be used as surface protective coatings for machinery, tools and chemical pipelines.
