strontium phosphate is an inorganic chemical with a molecular formula of [Sr3PO4]. It exists naturally as a white crystalline powder. It can be synthesized by precipitation, sol-gel, and hydrothermal methods. It is a highly reactive compound and readily forms compounds with metals or non-metals. Phosphorus and oxygen combine to form the phosphate ion. Strontium is a member of the alkaline earth metals group which are elements that can easily lose electrons and exist as cations. When strontium combines with phosphate, it loses three electrons and exists as an anion. Since strontium combines with the ion of phosphate with equal and opposite charges, they form an ionic bond.

The presence of strontium in the ionic compound increases the biological activity of phosphate. This can lead to several effects such as increased bone mineral density, gene expression enhancement, reduced tumor growth, and angiogenesis. It also enhances the reactivity of calcium phosphate cement and can be used in vascularized tissue engineering.

To make strontium phosphate, the element is first added to water with proper proportions of other reactants. This mixture is then heated under high temperature and pressure to produce the ionic compound. Afterward, it is mixed with activating compounds to form the hydrate and then further treated to produce the final product. It is a highly reactive compound and may cause fires or explosions if it comes into contact with moisture or other substances. It is not recommended to be used in foods, medicines, and other human consumables.
