摘要：
The devitrification behaviour of Li2O.4GeO2 glass examined by differential thermal analysis and X-ray diffraction is reported and discussed. Li2O.4GeO2 glass was found to devitrify in two steps. In the primary transformation microcrystallites of Li2Ge4O9 are crystallised in an amorphous matrix. In the second transformation well shaped Li2Ge4O9 Crystals are formed. The activation energies of the two stages are found to be 698 and 502 kJ/mol respectively.
