Aluminum dihydrogen phosphate (Al(H2PO4)3)-Powder

Characteristic

Aluminium dihydrogenphosphate describes inorganic compounds with the formula Al(H₂PO₄)₃.xH₂O where x = 0 or 3. They are white solids. Upon heating these materials convert sequentially to a family of related polyphosphate salts including aluminum triphosphate (AlH₂P₃O₁₀.2H₂O), aluminium hexametaphosphate (Al2P6O18), and aluminium tetrametaphosphate (Al₄(P₄O₁₂)₃). 

Chemical formula：AlH₆O₁₂P₃

Molar mass：317.939 g·mol⁻¹

Appearance：white solid

Density：2.37 g/cm³

Application

Some of these materials are used for fireproofing and as ingredients in specialized glasses.
