A ZLAS glass of composition 61Si02.6A1203.10Mg0.6Zn0.12Li20.5Ti02 (mol%) has been prepared by a melting process and investigation as far as cristallization is concerned. Glass-ceramic is easily obtained because glass shows a high tendency to crystallize starting from 700 deg C. The titanates of Mg and Zn develop from the phase-separated glass, soon after Tg, and grow to form nucleation centres for the other crystalline phases. The evolution from phase-separated glass to glass ceramic has been followed by many thermal, diffractometric, spectrosocpic, and microscopic techniques.
