Abstrakt: 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 Ca5(PO4)3(OH), octacalcium phosphate Ca8H2(PO4)6⋅5H2O, and brushite CaHPO4⋅2H2O. The phase composition of a powder synthesized from magnesium acetate included struvite MgNH4PO4⋅6H2O. 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 Ca5(PO4)3(OH), vitlockite Ca18Mg2H2(PO4)14, and struvite MgNH4PO4⋅6H2O. 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.
