Powder mixtures prepared by mechanical activation from synthetic hydrated acidic calcium phosphates Ca(H2PO4)2 · H2O and CaHPO4 · 2H2O were used to obtain resorbable ceramic in the system Ca (PO3)2–Ca2P2O7. The phase composition of the ceramic after firing in the interval 700 – 1000°C was represented by biocompatible and bioresorbable phases: calcium polyphosphate Ca(PO3)2, tromelite Ca4P6O19, and calcium pyrophosphate Ca2P2O7. The obtained materials can be used to fabricate resorbable implants for regenerative treatment of defects of bone tissue.
