Abstract
A series of amorphous and crystalline lithium germanates containing up to 25 mol% Li2O, are studied by FTIR. The glasses are found to devitr ify in a number of steps. In the primary step, above T-g. the glasses undergo a transformation with a strong exothermic effect which corresp onds to almost no crystal growth. The nature of this process is invest igated and discussed.
