- Аннотация: β-Tricalcium phosphate (β-Ca3(PO4)2) based ceramics with a relative density of 20–21%, grainsize from 200 to 600 nm, and compressive strength from 1.6 to 1.8 MPa have been produced by 1000°C firingof cement stone prepared from a powder mixture having a Ca/P molar ratio of 1.5 and consisting of hydroxyapatite(Ca10(PO4)6(OH)2), calcium citrate tetrahydrate (Ca3(C6H5O7)2·4H2O), and calcium dihydrogenphosphate monohydrate (Ca(H2PO4)2·H2O). The mixing liquid used to initiate chemical binding reaction in thepowder mixture was distilled water. The phase composition of the cement stone included brushite (CaHPO4·2H2O) and unreacted starting materials. The presence of platelike calcium pyrophosphate (Ca2P2O7)particles, formed from platelike brushite (CaHPO4·2H2O) particles, impeded densification of the ceramicsduring firing and ensured the formation of an ultraporous structure. The submicron-grained microstructureand phase composition of the β-Ca3(PO4)2-based ceramics resulted mainly from heterophase interactionsbetween the products of thermal decomposition of cement stone components. Offering sufficient strength,biocompatible and bioresorbable ultraporous submicron-grained β-Ca3(PO4)2-based ceramics can be recommendedfor use in regenerative medicine for bone tissue defect repair.
