- Аннотация: Detailed theoretical and experimental studies of ionic equilibria in buffered solution containing brushite or α-TCP were undertaken to determine the area of coexistence of OCP and brushite in T-pH space. These results were used to get the conditions of synthesis of OCP-phases. Various techniques and conditions of solution synthesis have been tested for obtaining of intercalated. The pure product of substitution Са8(НРО4)2-хRx(PO4)4•5H2O (R = Suc) with x = 0,8 ÷ 0,9 was acquired by hydrolysis of α-TCP in the succinic buffer, but the ways to control the degree of substitution x have not been found yet. Suc@OCP demonstrates greater resistance to thermolysis compared to pure OCP. The differences in kinetics and mechanism of their decomposition lead to a different micromorphology of intermediate apatitic product, which is stable up to 630°C in the case Suc@OCP. Variation in phase composition of the thermolysis products leads to the fact that the ceramics based on heat-treated Suc@OCP are denser and apparently stronger than ones based on heat-treated pure OCP. It is shown that slip-casting in 3D-printed plastic forms provides the best reproduction of complex macroporous architecture.
