摘要

Calcium hydroxyapatite (Ca_(10)(PO_4)_6(OH)_2;CaHAp)was prepared from teh cation-exchange of Na~+ in the gel consisting of sodium alginate and Na_4P_2O_7 with Ca~(2+) from the mixture of Ca(CH_3COO)_2 and Ca(NO_3)_2 in an aqueous solution at pH 10 although it had been already reported that CaHAp couldj be prepared with the employment of CaCl_2 at pH 6.5,which rather afforded calcium chlorapatite(Ca_(10)(PO_4)_6Cl_2).
