Study of Heat Treatment Parameters in Obtaining Glassceramic Materials with the Addition of Industrial Wastes

Abstract

The production of materials from crystallization of glass, called glassceramic, have proved interesting by the possibility of development of different microstructures, with reduced grain size and the presence of residual amorphous phase in different quantities. The method that uses the differential thermal analysis (DTA) provides research on the material properties over a wide temperature range, it ́s widely applied to crystallization processes of glassceramic materials. Within this context, this paper aims to study the kinetics of nucleation and crystal growth in glassceramic materials in the system SiO2-Al2O3-Li2O, obtained with the addition of mineral coal bottom ash as source of aluminosilicates, through the technique of differential thermal analysis.
