Aluminum

Alumina is an important chemical compound of aluminum with two structural forms like α Al 2 O 3 and ϒ Al 2 O 3 The α Al 2 O 3 occurs in nature as corundum which is resistant to water and acids and uses in Gems The γ alumina is distorted less dense soft with high surface tension in the liquid form
