Abstract
Fe-57 Mossbauer spectroscopy was used to observe the crystallization p rocess in glasses with composition denoted by [0.50SiO(2), 0.45Na(2)O, 0.05CaO] (100-x)(Fe2O3)(x) With x equal to 4, 10 and 16 mol%. It is s hown that Mossbauer spectroscopy is a very suitable technique for dete cting and checking the very early stages of crystallite formation in a morphous materials. The crystallization process was observed and quali tatively analysed by means of classical volume nucleation theory.
