Active Aluminium Oxide Appearance White Non poisonous No foul

Properties: The product is white crystalline powder, it is obtained by calcining aluminum hydroxide. Although there are many variations of alumina crystals, Active Aluminium Oxide that is the stablest and most used is α -alumina. Active Aluminium Oxide It has high melting point, is thermally stable, Active Aluminium Oxide has diamond hardness. Moreover, Active Aluminium Oxide has high electric resistance and is stable against alids and alikalis.

Application: Used for adsorbent desiccants and catalyst carriers.
