Customized packages are accepted Note: we can customize new aluminum oxide products according to customer needs Aluminum oxide is a stable oxide of aluminum, with the chemical formula Al2O3. Also known as bauxite in mining, ceramics, and materials science. Aluminum oxide is a white solid that is insoluble in water, odorless, and extremely hard in nature. It is easy to absorb moisture but not deliquescent (burnt does not absorb moisture). It has characteristics such as high melting point, high hardness, high fire resistance, and excellent electrical insulation performance, and is widely used in fields such as ceramics, refractory materials, grinding materials, electronic materials, etc. High temperature calcined alumina powder products have a high melting point, excellent mechanical strength, hardness, high resistivity, and thermal conductivity. It can be widely used in industries such as electronic equipment, structural ceramics, refractory materials, wear-resistant materials, polishing materials, etc. Product Application Polishing High purity aluminum oxide powder used for precision polishing has low impurity content, small particle size, high polishing efficiency, and high polishing glossiness. It is widely used in the precision polishing industry and can meet the precision polishing requirements of products with low impurity content. Suitable for precision polishing of materials such as sapphire, glass, metal, semiconductor, plastic, etc., making their surfaces less prone to defects. Ceramic industry Aluminum oxide can be widely used in the production of ceramics. Aluminum oxide ceramics have many e

Gamma Alumina Sphere for Anthraquinone Hydrogenation Catalyst Carrier

Product Oil drop activated alumina sphere Crush Strength 50min N/p Packed Bulk Density 540-580 G/L Surface Area 190-230 M2/G Appearance White Sphere Pore Volume 0.70min ML/G Usage: Anthraquinone hydrogenation catalyst,Desulfurization,Olefin acetylene removal,Alkyl benzene sulfate was prepared,LAS,Propane dehydrogenation. Propane dehydrogenation includes direct dehydrogenation (PDH) and oxidative dehydrogenation (OPDH). The catalyst systems of propane oxidative dehydrogenation are mainly concentrated in the systems with vanadium, chromium, cobalt, nickel, molybdenum, platinum and other transition metals as active components, as well as rare earth metal elements lanthanum and cerium, non-metallic carbon-based, boron nitride and so on Adsorption removal At the same time, it is also used in propane dehydrogenation,anthraquinone hydrogenation, desulfurization, olefin deacetylene and gas purification and other chemical and medical environmental protection hydrogenation catalytic and adsorption removal fields.
