A series of amorphous and crystalline lithium germanates containing up to 25 mol% Li20 are studied by FTIR. The glasses are found to devitrify in a number of steps. In the primary step, above Tg the glasses undergo a transformation with a strong exothermic effect which corresponds to almost no crystal growth. The nature of this process is investigated and discussed.
