Abstract

Trivalent chromium in transparent glass-ceramics (73.6 SiO₂ :11.8 Al₂O₃:4.2 Li₂O: 7.0 ZnO: 1.6 TiO₂: 1.5 ZrO₂: 0.3 As₂O₃: 0.024 Cr₂O₃ mole%) enters mainly the gahnite phase after an equilibrium has been reached. The intermediate phase during heat treatment is of virgilite-type Li_xAl_xSi_3-xO₆. This glass-ceramic has been studied by X-ray diffraction and time-resolved spectroscopy at low temperatures under laser excitation.
