ИСТИНА

The manufacture of nano-sized bioceramic particles poses an interest for the development of novel bone implants. The researchers have accepted the idea of highly resorbable material usage which demands the synthesis of calcium phosphates with Ca/P ratio < 1.5. The usage of non-aqueous medium for the calcium phosphate synthesis is motivated by the several reasons. Firstly, phase transitions caused by high basicity of ortophosphate ion in aqueous environment lead to the impurities in the material. Secondly, pyro- and polyphosphate ions inhibit the crystallization of the material. Using non-aqueous solvents one can eliminate water influence and get more control on the material. Hence, the main goal of the work was the obtainment of calcuim phosphates in non-aqueous medium.
