Abstract

Transparent glass ceramics with Cr(III) were obtained by different thermal treatment of glass with composition (mol%) 73.6 SiO2,11.8 Al2O3, 4.2 Li2O, 7.0 ZnO, 1.6 TiO2, 1.5 ZrO2, 0.3 As2O3, 0.024 Cr2O3, melted under various conditions. Parallel measurements of X-ray diffraction, optical and EPR spectra reveal the different formation ofgahnite from precursor glass or petalite-like phase.
