The results of synthesis and physicochemical analysis of ceramic and composite materials based on calcium phosphates are presented. The structure and properties of the materials by techniques such as X-ray powder diffraction, scanning electron microscopy and microindentation was characterized. Influence of parameters of ultrasonic, hydrothermal and
thermal treatment on the properties of the synthesis products was investigated. The values of linear shrinkage, water absorption and porosity of ceramic samples were determined. The possibility of obtaining promising for use nanoceramics containing phase double phosphates of calcium and alkali metal, which has an unusual microstructure and high degree of
resorption was shown.
Key words: calcium phosphates, nanoparticles, chemical deposition, ultrasonic and hydrothermal synthesis, ceramics, bioresorption.
