The main highlights in this paper are about investigation of cation-dopped cements based on the calcium phosphate —magnesium phosphate system with a ratio of (Ca + Mg) / P = 2 containing 40 mol. % Mg for application in the reconstructive surgery. The powders were synthesized by the method of deposition from a salt solution, the powders were certified using the X-ray phaseanalysis (XRD), the main phases were the magnesium-substituted vitlokite phase (Ca2,589Mg0,411PO4), magnesium oxide MgO, and stanfeldite (Mg3Ca3(PO4)4. The setting time of cement samples with mixing phosphate fluid is 6–9 min; the high mechanical properties are exhibited by the samples with a content of 0,5 mass % Zn (26,5 ± 1,3 MPa).
