Glass-ceramic enamels derived from the Li2O-Na2O-Al2O3-TiO2-SiO2 system

Abstract

The results of research on the conditions for obtaining model glass-ceramic enamels, derived from the basic Li2O-Na2O-Al2O3-TiO2-SiO2 system, by varying the initial composition and thermal treatment conditions, are presented in this paper. Segregation of the crystal phases in the glassy-matrix was carried out during subsequent thermal treatment. The formation of different crystal phases was evidenced through the results of differential-thermal analysis and X-ray powder diffraction analysis.

U radu je predstavljeno istraživanje uslova dobijanja modelnih staklo-kerami čkih emajla, izvedenih iz osnovnog sistema Li2O-Na2O-Al2O3-TiO2-SiO2 promenom polaznog sastava i uslova toplotne obrade. Izdvajanje kristalnih faza u staklastoj matrici ostvareno je tokom naknadne toplotne obrade. Obrazovanje različitih kristalnih faza utvrđeno je na osnovu rezultata diferencijalno-termijske analize i metodom rendgenske difrakcije.
