Abstract

The aim of this research is to show the effect of zirconium silicate addition on sintering and physicochemical properties of glass-ceramic materials from the SiO2–Al2O3–Na2O–K2O–CaO–MgO–BaO system. This paper presents the results of the most important techniques used to understand the sintering process, i.e. thermal differential analysis, dilatometry measurements and hot-stage microscopy. Additionally, the following techniques have been used: X-ray diffraction (XRD) and scanning electron microscopy with a micro-analyser (SEM-EDS), and in order to obtain surface physicochemical properties: laser confocal microscopy, glossmetry, and spectrophotometry. By changing the initial composition and thermal treatment of glass-ceramic materials it is possible to shape parameters of final products which leads to obtaining a great variety of applications.
