摘要：

Calcium hydrogen phosphate (CaHPO4·2H2O, DCPD) is one of the main inorganic components of bone and teeth[1]. Since the anticaries effect of fluoride was found in 1940's, much effort was made in the aspect of the fluoridation of HAP[2].However, the effect of fluoride ion on the solubility of DCPD remains unclear. This study investigated the hydrolysis characteristic of DCPD in NaF solutions and the solubility of the hydrolysates.
