About Product


The product is suitable for various aluminum compounds, as flame retardant additives for flammable materials such as plastics


The so-called aluminum hydroxide actually refers to the hydrate of aluminum oxide. For example, the white colloidal precipitate obtained by adding ammonia or alkali to the aluminum salt solution has variable water content and uneven composition, and is collectively referred to as hydrated alumina. Only by passing CO2 in the aluminate solution (containing Al(OH)4-ion) can the real aluminum hydroxide be obtained.


Crystalized aluminum hydroxide is different from hydrated aluminum oxide. It is hardly soluble in acid and will not be dehydrated when heated to 373K. It can be converted into aluminum hydroxide (AlO(OH)) after heating at 573K for 2 hours.


Aluminum hydroxide is an amphoteric hydroxide. Because of its two ionization forms, it is not only a weak acid, which can have the acid formula H3AlO3, but also a weak base, which can have the basic chemical formula Al(OH)3. Aluminum hydroxide is amphiphilic and can react with acids and alkalis. The acidity of aluminum hydroxide is that it is a Lewis acid that can be added with OH-, thus reflecting the basicity of Al(OH)3. Due to the presence of two ionizations, two salts can be produced: two salts of aluminum:


⒈aluminum salt: Al3+ AlCl3 , KAl(SO4)

2·12H2O (alum).


Their aqueous solutions are acidic due to the hydrolysis of Al3+. AgNO3 and dilute nitric acid are added dropwise respectively. The white precipitate is Cl-; the light yellow precipitate is Br-; the yellow precipitate is I-2. Metaaluminate, AlO2 - NaAlO2,KAlO2. Their aqueous solutions are alkaline: AlO2- + 2H2O → Al(OH)3 + OH- When the two types of salts are mixed, a double hydrolysis reaction occurs, forming  Al(OH)3 Al3+ +Al2-3 6H2O == 4Al(OH)3↓ Aluminum hydroxide mainly has four specifications: 325 mesh, 800 mesh, 1250 mesh, and 5000 mesh. White powdery solid. Almost insoluble in water, it can condense suspended solids in water and adsorb pigments.
