　　Calcium deficient hydroxyapatite (CDHA) powder having the size in 100-200 nm were synthesized by using reverse micelle as a template system.Calcium nitrate and ammonium phosphate at a fixed Ca/P molar ratio of 1.5 were used as the aqueous phase, cyclohexane as the oil phase, and Span 80 as the surfactant.The reaction was carried out at room temperature for 24 h.The prepared CDHA powders were further calcined at 1000℃ to obtain tricalcium phosphate (TCP).
