摘要
A ceramic the phase composition of which included tricalcium phosphate, calcium magnesium orthophosphate, and magnesium pyrophosphate was prepared from nanosized powders synthesized via chemical deposition from 1 M aqueous solutions of ammonium hydrogen phosphate and calcium and/or magnesium acetates. The XRD data showed that the phase composition of a powder synthesized from calcium acetate involved calcium hydroxyapatite Ca-5(PO4)(3)(OH), octacalcium phosphate Ca8H2(PO4)(6).5H(2)O, and brushite CaHPO4.2H(2)O. The phase composition of a powder synthesized from magnesium acetate included struvite MgNH4PO4.6H(2)O. The phase composition of a powder synthesized from a solution containing calcium and magnesium acetates at a Ca : Mg ratio of 9 : 1 included hydroxyapatite Ca-5(PO4)(3)(OH), vitlockite Ca18Mg2H2(PO4)(14), and struvite MgNH4PO4.6H(2)O. The ceramic materials containing bioresorbable and biocompatible phases of calcium and/or magnesium phosphates can be used to obtain bone implants for the treatment of bone tissue defects.
