Calcium sulfate-based powders with magnesium substituting for calcium cations in amounts of 10, 20, and 40 mol % were synthesized by the mechanochemical method. The phase composition of the products, the solubility, and the compressive strength of the obtained cement materials mixed with water were studied. It was shown that the solubility in the physiological saline increases, while the strength...
Sulfate-substituted hydroxyapatite materials with a degree of substitution of up to 20 mol % (Ca10(PO4)(6 – 0.06x)(SO4)0.09x(OH)2, x = 0, 0.1, 0.5, 1, 5, 10, and 20) were synthesized. For substitutions of 0, 0.1, 0.5, and 1 mol %, a single-phase material with the apatite structure is formed. On further increase in the concentration of SO42− groups up to 20 mol %, a second phase, CaSO4, is formed;...
