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