✦ Synopsis
Transparent glass ceramics with Cr(III) were obtained by different thermal treatment of glass with composition (mol%) 73.6 SiO2, 11.8 A120,, 4.2 Li20, 7.0 ZnO, 1.6 TiO2, 1.5 ZrO2, 0.3 AszOs, 0.024 Cr203, melted under various conditions. Parallel measurements of X-ray diffraction, optical and EPR spectra reveal the different formation of gahnite from precursor glass or petal&e-like phase.
