Biphasic tricalcium phosphate, BCP, was originally reported as tricalcium phosphate, but X-Ray diffraction techniques showed that the material was an intimate mixture of two phases, hydroxyapatite, HA, and β-tricalcium phosphate.

Thus phosphate minerals, in which phosphorus is oxidized in the phosphate group, PO 4, are part of a tight geochemical cycle that includes the biosphere, rather like the carbon cycle. Apatite (Ca 5 (PO 4 ) 3 F) is a key part of the phosphorus cycle.

Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides.

However, many urinary stones—including struvite stones—also contain calcium phosphate in the mineral form of apatite, and this mineral retains imprints of bacteria , suggesting that it would be a likely source for retention of infectious agents that could be released during surgery.
