Abstract	Calcium hydrogen phosphate dehydrate (DCPD, CaHPO4•2H2O) reacts with fluoride ion in a solution and forms fluorapatite (FAp, Ca10(PO4)6F2) [1,2]. This reaction is utilized in the development of dental phosphate cements [3]. We have previously applied the reaction to pre-concentration of fluoride in water [4] and gypsum [5]. In previous study, we have appeared that DCPD does not react with fluoride ion directly, but forms a precursor particle with 20-30 nm on surface of the DCPD particle [6]. The precursor particle formation needs to 2-3 hours, that is one of problems of the DCPD reaction when applying the DCPD reaction to environmental issues, such as water treatment [7]. Hybridization of calcium phosphates is one of the approaches for improvement of the property. Aslanidou et al. [8] carried on the preparation of hybrid of HA/DCPD for controlling dissolution rate and mechanical properties. The present work was an investigation for the effect of hydroxyapatite (HA, Ca10(PO4)6F2) on the reaction of DCPD. The HA was mixed with DCPD or coated on the DCPD particle. Simulated body fluid (SBF, Kokubo Solution) [9] was selected for the method of the coating of HA.
