Abstract

The effect of fluoride on the hydrolysis of tetracalcium phosphate (TTCP; Ca₄(PO₄)₂O) in 0.1 mol/l KH₂PO₄ containing 62-83 mmol/l KF was studied with the help of X-ray fluorescence measurements. Fluorine X-ray emission and absorption spectra of the final product of hydrolysis and reference samples (CaF₂ and Ca₅(PO₄)₃F) were measured at Beamline BL-2C of Photon Factory (PF, Tsukuba). Based on these measurements we concluded that hydrolysis of TTCP in the presence of KF converts it into fluorapatite. Formation of CaF₂, which is often found in the hydrolysis of hydroxyapatite at high fluoride concentration, was not observed.
