Abstract
Nucleation of crystals in sodium-calcium-silicate glasses of the quasi-binary metasilicate section CaO · SiO2-Na2O · SiO2 has been investigated by the development method. The maximal stationary rate of crystal nucleation in the composition range Na2O · 2CaO · 3SiO2-Na2O · CaO · 2SiO2 increases substantially with the increase of the sodium oxide content. It was assumed that in this range, along with nucleation of crystals of solid solutions based on Na2O · 2CaO · 3SiO2, nucleation of crystals 2Na2O · CaO · 3SiO2 could occur as well. Nucleation of crystals of the above two phases in glass of the composition 28.4Na2O · 21.2CaO · 50.4SiO2 (mol %) from the middle of the range Na2O · CaO · 2SiO2-2Na2O · CaO · 3SiO2 has been studied.
