Abstract
Based on theoretical and experimental analysis of ionic equilibria in buffer solutions, we have found conditions for octacalcium phosphate (OCP), Ca8(HPO4)2(PO4)4 ∙ 5H2O, synthesis. Succinate-substituted OCP, Ca8(HPO4)2–хSucx(PO4)4 ∙ 5H2O, with x = 0.8–0.9 has been synthesized at pH 5.5 and t = 60°C in 3 h via α-TCP hydrolysis in a 0.25 M succinic buffer solution. The synthesis product is more stable to thermolysis than is pure OCP: the apatite-like product is stable up to 630°C. The succinate@OCP powder has been used as a filler for poly(ethylene glycol)diacrylate-based hydrogel in producing a composite implant by stereolithographic 3D printing.
