Aluminum Hydroxide Advantages And Processing Equipment

The chemical formula of aluminum hydroxide is Al(OH)3, which is a hydroxide of aluminum.It is a kind of alkali, because it shows a certain degree of acidity, it can also be called metaaluminate monohydrate (HAlO2•H2O), but when the actual aqueous solution reacts with the alkali, the tetrahydroxyaluminate Al(OH) is formed 4-.
