Application of α Alumina and γ Alumina in the Catalysis of Petroleum Refining
What does alumina mean? Alumina Al2O3 is an inorganic compound. It has a high hardness and melting point of 2054degC, as well as a boiling point at 2980degC. It’s an ionic crystal which can be ionized at elevated temperatures. This is why it is frequently used for the production of refractory material. Alumina for industrial […]

What does spherical allumina mean? The high-temperature spraying process produces high-sphericity spheres of alumina. When used in filler material for rubber, plastics, or ceramic raw materials it shows exceptional performance. This ultrafine, spherical, aluminum has many excellent properties, including high corrosion resistance, heat resistance, high hardness and strength, wear resistance as well as oxidation resistance. […]
Read MoreActivated Alumina and Uses
What activates alumina? Activated Alumina is also called activated alu, which contains alumina in its catalyst. The material is porous and high-dispersion, with large surfaces and micropores. Because of its excellent properties for catalysis (adsorption performance and surface activity), it’s widely used to be a catalyst carrier or catalyst for chemical reactions. The sphere activated […]

What is alumina dioxide? Alumina oxide, a novel type of high purity material, plays an increasing role. Alumina oxide, a fine white powder that has uniform particle sizes, easy disperse and chemical properties. This is the raw material used to make heat-resistant or wear-resistant products. There are many uses for alumina oxide. They can be […]
Read MoreWhat is alumina used for?
Alumina properties High resistance to heat: alumina may be used in an oxidation-reduction atmosphere up to 1650degC (2900degF), or in vacuum environments as high as 2000degC (3600degF). Wear resistance: Alumina is an extremely durable ceramic that has outstanding wear resistance. Alumina is a great choice for products or inserts that require wear resistance. Electrical insulators: […]
