Ponomarchuk H. Alkali-free glasscrystalline materials with reaction forming structure

The dissertation is dedicated to advancing of technology receiving of celsian glassceramics with reaction forming structure, substantiation of chemical and material composition of mixtures for its deriving, research of temperature-temporal requirements of sintering. Is established, that celsian glassceramics is obtained by sintering of composition mixture " glass - crystalline filler". The refractory alumina is eliminated from composition of a basic glass. It is introduce in composition of crystalline filler (alumina or kaolin). The relation between oxides BaО, Al2O3 and SiО2 in composition mixture should be close to a relation between them in celsian. The series of practical compositions of mixtures for deriving of celsian glassceramics are designed. The basic technological parameters of its deriving are established
