- Аннотация: The aim of this work was to synthesize and study the properties of newberitepowders derived by interaction of aqueous solutions of magnesium chloride and dibasic sodium phosphate to produce resorbable ceramic materials.The synthesis was carried out by precipitation from aqueous solutions of dibasic sodium phosphate and magnesium chloride to produce highly dispersive powders with a narrow particle distribution. For the first series of synthesis of newberite powder with a chaotic particle morphology, the solution of dibasic sodium phosphate was added to the solution of magnesium chloride. In the second series of the synthesis of the powder with particles in the form of flowers , solution of magnesium chloride was added to the dibasic sodium phosphate solution. It has been established that a powder of newberite during firing at temperature in the range 800 C to 1200 formed a porous ceramic material based on the high temperature modification of magnesium pyrophosphate Mg2P2O7.Magnesium phosphates ceramic with magnesium cations coupled with condensed phosphate ions play a significant role in the bone remodeling process, affecting the early stage of bone regeneration through stimulating osteogenic differentiation, prohibiting osteoclastic activity, and transforming into mechanically enhanced hydroxyapatite bone tissues. Osteoconductivity of the implants and sufficient strength are also achieved by obtaining a macroporous material with a specific architecture (gyroid and Kelvin), in which up to 70% of the total volume is connected pores. For these bioceramics, the composition of suspension for DLP-printing is revealed, rheological, mechanical and toxicological tests are carried out and in vivo study is done.Acknowledgements: This work was supported by the Russian Foundation for Basic Research (project No 19-38-90274).
