| Abstract Scope |
Materials based on calcium pyrophosphate Са2Р2О7 with a molar ratio Ca/P=1 and calcium polyphosphate Са(РО3)2 (in an amount up to 50%), having a molar ratio Ca/P=0.5 meet the requirements that necessary for application in regenerative medicine. Calcium phosphates with a molar ratio Ca/P=1 (Са2Р2О7.хН2О, СаНРО4.2Н2О, СаНРО4) synthesized from solutions, in pastes, or in conditions of mechanical activation were used as precursors of calcium pyrophosphate Са2Р2О7. Calcium phosphates with a molar ratio Ca/P=0.5 (Са(РО3)2.хН2О, Са(Н2РО4).Н2О, Са(NH4)2P2O7, СаH2P2O7) were used as precursors of calcium polyphosphate Са(РО3)2. Powder mixture comprising precursors of the calcium pyrophosphate and polyphosphate phases at a given molar ratio in the range 0.5<Ca/P<1 were used for production of ceramic materials in the system Са2Р2О7-Са(РО3)2. The target phases are formed as a result of thermal conversion and as a result of heterophase interaction in the investigated mixtures.
