What is Spherical alumina? Spherical alumina has the characteristics of high sphericity and high content of α-phase alumina, and it shows the superior performance when used as a filler for rubber, plastics, and ceramic raw materials.It is a kind of powder obtained from natural quartz powder. Its phase, crystal shape and shape change instantly, from solid to molten to solid, from crystal to amorphous, and from irregular angular particles to regular spherical particles. Spherical quartz powder is the instantaneous melting of irregular quartz powder particles under the action of surface tension.
Characteristics of Spherical alumina 1. high filling property It has high sphericity and wide particle size distribution and can be used to fill rubber and plastic with high density, thus obtaining a mixture with low viscosity and good fluidity. 2. High thermal conductivity Because it can be filled with high density, compared with crystalline silicon powder, it can obtain a mixture with high thermal conductivity and good heat dissipation. 3. Low abrasion resistance Because of its spherical appearance, it greatly reduces the wear of mixer, molding machine, mold, and other equipment and can prolong the service life of the equipment. Application of Spherical alumina Spherical Aluminum Oxide has a wide range of functions: 1. Coating: ceramic coating, wear-resistant coating, plasma spraying. 2. Ceramics: transparent ceramics, biological ceramics, alumina ceramics. 3. Petrochemical industry: high-efficiency catalyst, catalyst carrier, automobile exhaust purification materials. 4. Polishing materials: submicron/nanometer abrasive, monocrystalline silicon wafer grinding, precision polishing materials. 5. Lighting: long afterglow phosphor raw materials and rare earth tricolor phosphor materials, high-pressure sodium lamp tubes, LED lamps, etc. 6. Electronics: integrated circuit substrates, single-crystal materials, far infrared materials. 7. Cosmetics: cosmetic fillers. 8. Inorganic membrane materials.
