High-strength glass-ceramic from ZABS system modified with transition metal oxide

Abstract

The designed glass-ceramic from the ZABS (ZnO-Al2O3-B2O3-SiO2) glass-forming system were used for the experiment. The main purpose of this study was to investigate the effect of copper oxide on the structural and mechanical properties of a glass-ceramic, with willemite as the main crystalline phase. Generally, transition metal (TM) oxides significantly affect the crystallisation characteristics, subsequently influencing the thermal behaviour of the glass-ceramics. Both samples were tested to determine the type of structural changes that occur after the introduction of the modifier – copper oxide. The type of deformations occurring during scratch-test, were also checked in terms of plastic flow, structural densification and mechanical properties (Young's modulus and hardness).
