Characterization of Ruby Color in Some Special Glass Compositions and Their Corresponding Glass–Ceramic Derivatives

Abstract

AbstractGlasses of the system B2O3 – PbO – MgF2 – P2O5 – SiO2 containing different dopants from Cr2O3, MnO2, and SeO2 were prepared by the conventional melt quenching method. The prepared glasses were characterized by their ruby color caused by the effect of dopants. The amorphous nature of the prepared glasses was confirmed by x-ray diffraction (XRD). Differential thermal analysis (DTA) was used to design a heat treatment program to obtain their corresponding transparent glass–ceramic derivatives from parent glasses. Collective spectroscopic measurements were applied to evaluate the optical properties of glasses and their corresponding glass–ceramics. XRD and morphological analysis of glass–ceramics indicated the formation of two crystalline phases (PbO(B2O3)2) and (Mg2BO3F). Optical analysis confirmed the stability of the color even after heat treatment. The chromaticity coordinates indicated a deep red color related to the chromium dopant and red wine color for selenium and manganese dopants.
