Formation of Strontium‐Stabilized β‐Tricalcium Phosphate from Calcium‐Deficient Apatite

A series of strontium-stabilized β-tricalcium phosphate (β-TCP) was prepared via the aqueous precipitation method, and characterized by X-ray diffraction and infrared fourier spectrometer techniques. The general principle of preparing calcium-deficient apatite and thereby heat-treating the resultant apatite above 700°C to form single-phase β-TCP was attempted to create strontium-substituted β-TCP. The results have proved that single phase β-TCP could be formed with the substituted strontium with only an influence on the increase in lattice constants with an increase in the concentration of strontium. Further, it is also stated from the present findings that strontium has a specific role in the crystallinity of the resultant β-TCP.
