Abstract
Crystal phases precipitated and activation energies for crystal growth duri ng heat treatment were determined for the glasses in the systems Li2S-SiS2 and Li2S-SiS2-LixMOy (LixMOy=Li3PO4 and Li4SiO4). The activation energies E (a)for Li2S-SiS2 sulphide glasses ranged from 177 to 270 kJ/mol and similar values were observed for oxysulphide glasses with the addition of Li(x)MO( y)less than or equal to 20 mol%. E-a values for these glasses were influenc ed by crystal phases precipitated from the glasses. The composition depende nce of E-a values was opposite to that of difference in temperature of crys tallisation and glass transition. This inverse correlation was understood f rom a viewpoint of these sulphide and oxysulphide systems behaving as the f ragile liquids.
