β-tricalcium bis (orthophosphate) [Ca3(PO4)2] (β-TCP) was mechanochemically treated with mortar grinder. The ground β-TCP was hydrolyzed in organic-aqueous binary systems (octane-H2O, and octanol-H2O) to give Ca-deficient hydroxyapatite (HAp) involving small amount of CO32- ions. The rate of the hydrolysis in octane-H2O binary system was faster than that in ammonium aqueous solution, however, shape of the products in the binary system did not so much differ from that in the aqueous system. Fluorination of the ground β-TCP proceeded much faster than that of β-TCP to form fluoridated hydroxyapatite (FHAp).
