Glass–ceramic materials due to the various physical and chemical parameters have a more and more wide application in various areas of engineering. This paper presents a glass–ceramic material originating from the Al2O2–SiO2–Na2O–K2O–CaO/MgO modified by the addition of barium oxide. For the oxide composition which the molar ratio of SiO2/Al2O3 is constant and equal to 6.42, and containing 0.375 mol%...
