China Factory Aluminium Oxide Powder Nano Al2O3 Alumina Powder Price

The subsonic air atomization method for atomizing aluminum powder has been adopted, and the pressurized water atomization method has also begun to enter the production sequence. The products are both irregular and spherical. In the production of aluminum powder and aluminum slurry by ball milling, both dry process and wet process are adopted by manufacturers. The products are floating aluminum powder and aluminum slurry, non-floating aluminum powder and aluminum slurry. Water-dispersed aluminum slurry suitable for water-based coatings has long been available, and aluminum slurry in the form of alloy, such as zinc-aluminum slurry, has also been produced.

The aluminum powder is silvery white metal powder, with spontaneous combustion temperature of 5900 ℃ and dust explosion limit of 40mg/m3. Do not touch dilute acid or strong alkali. When a large amount of dust is damp, it will naturally heat up. The mixture of aluminum powder and other metal oxides will react violently or catch fire in case of fire. Mixing with halogen elements will cause fire. Explosive reactions may occur when heated or rubbed with halogenated hydrocarbons.
