| Résumé: | In this paper, sodium borosilicates glasses were prepared by melting in air. These
heat-resistant transparent glasses have subjected subsequently isothermal treatments at
different times, which have transformed them at opaque glass (milky white color). Such
changes indicate that these glasses showed clearly phase separation (immiscibility). The
immiscibility region in a sodium borosilicate ternary system was investigated in this work, ie
to determine the regions from which some compositions can show phase separation. For
this we went through the conditions of thermodynamic equilibrium, which were translated
later by mathematical equations to find an approximate solution. The latter has been
translated in a simulation which was established thereafter to find the immiscibility regions in
this type of special glasses |
