Investigation of the Chemical and Thermal Characteristics of Glass-Ceramic Enamels

Sudhir Kumar Mishra and A. N. Singh

The results of an investigation of the chemical and thermal characteristics of glass-ceramic enamels, derived from the Li2O-Na2O-Al2O3-TiO2-SiO2 system, obtained by employing the methods of mathematical experiment planning, are presented in this paper. Adequate mathematical models, showing the dependence of the chemical and thermal stability on the chemical composition of enamel system, after different thermal treatment procedures, were obtained. Based on the testing carried out, it was concluded that in the obtained g1ass-ceramic enamels the chemical resistance is decreased, but at the same time, the thermal stability is increased, relative to reference coatings
