the chemistry and binding properties of aluminium phosphates

An Overview of Phosphates and Their Uses

The term phosphate refers to any one of a wide variety of chemical compounds that contain phosphorus, a naturally occurring mineral, bonded together with oxygen. The term is used both in inorganic chemistry and organic chemistry. In inorganic chemistry, the phosphate ion combines one phosphorus atom with three or four oxygen atoms, forming the base for many different salts.
