General description
Gamma-phase Al2O3 is one of the several crystalline phases of aluminum oxide, also known as alumina. It has a cubic crystal structure with a high degree of symmetry, characterized by a closely packed arrangement of oxygen and aluminum ions, and tends to be highly porous. Our aluminum oxide nanopowder in the gamma phase is a high-purity product with 99.95% purity and an average particle size of 5 nm. This nanopowder is characterized by its high surface area, excellent dielectric properties, and resistance to corrosion and wear. Our aluminum oxide nanopowder is produced using advanced manufacturing techniques, ensuring uniform particle size and high purity.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product has been enhanced for energy efficency. Click here for more information.
Application
Our gamma phase alumina nanopowder is useful in a variety of applications. Its high purity and small particle size make it an excellent catalyst and catalyst-support for chemical reactions, including dehydration, isomerization, hydrogenation, oxidation, reforming, and Fischer-Tropsch synthesis. Because of its porosity, it has many uses in pharmaceutical and industrial manufacturing processes as an adsorbent and desiccating agent. In addition, gamma-phase Al2O3 is a widely used material in the field of electronics due to its high dielectric constant, low dielectric loss, and excellent electrical insulation properties. Its ability to store electrical charge, retain its properties over a wide range of frequencies, and withstand high voltages make it an ideal choice for use in a wide range of electronic components, including capacitors, insulators, transformers, and high-frequency and high-voltage applications. The nanopowder′s hardness and stability make it suitable for use in wear-resistant coatings, and its resistance to corrosion and oxidation makes it a reliable material for high-temperature environments.
