Abstrakt: Abstract: The issues of synthesis of highly dispersed chemically homogeneous powders based on glaserite-like phases in the CaO–Na2O–P2O5–SiO2(GeO2) systems by a cryochemical method, including rapid freezing of a total salt solution, sublimation removal of ice, and subsequent thermolysis of a dehydrated salt precursor, are considered. The complex chemical composition of powders is necessary to create bioceramics from them with improved osteoplastic characteristics. Results of the synthesis of powders with submicron granulometry from solutions with different anionic composition are presented; the behavior of such powders during the sintering process is described.
