β-tricalcium bis (orthophosphate) [Ca3(PO4)2] (β-TCP) was mechanochemically treated with mortar grinder. The ground β-TCP was hydrolyzed in an aqueous ammonium solution (pH=11.0) at 90 to give Ca-deficient HAp involving small amount of CO3 2- ions. With an increase in grinding time of β-TCP, it was hydrolyzed easily. Well-crystalline Ca-deficient HAp was obtained after grinding of β-TCP for 7 hours and the successive hydrolysis.
