High Quality Alumina Powder Products >>>

Alumina is one of the most widely adopted ceramic materials. It is composed of Aluminum Oxide (Al2O3), which is the chemical compound of aluminum and oxygen. It offers electrical insulation, high temperature and chemical resistance, thermal conductivity and also provides superior abrasion resistance.

Purity levels for alumina range from 85% to 99.9%, supporting temperature ranges of: 100°C to 1600°C.

  High Purity Alumina Powder for Intraocular Lens

  On the basis of the salt water hydrolysis method, the "improved direct hydrolysis method" high-purity alumina preparation technology, namely the high-purity aluminum direct hydrolysis method, was successfully developed through technological innovation. This technology replaces aluminum foil with high-purity and high-activity aluminum powder, and replaces isopropanol with high-purity water. The aluminum powder reacts with pure water at a certain pressure and temperature to form aluminum hydroxide, which is then dried and roasted to obtain high-purity aluminum oxide.

  High Purity Alumina Powder for Transparent Ceramics

  The product uses high-purity alumina as the main material and is prepared by the hydrolysis method. It has the performance characteristics of high purity, stable particle size, and spherical powder shape. It can be used for the preparation of transparent and translucent alumina ceramic tubes, ceramic substrates, etc. Because the AO ceramic body has a high melting point, it is difficult to form, and its lattice constant is close to that of AO, so it can form a solid solution with AO. At the same time, they are variable-valence oxides. Due to the variable-valence effect, AO porcelain produces defects, activates the crystal lattice, and promotes the formation of porcelain.
