△ρ/ρ varies with temperature as T

isabout 0.5%ρ(R.T)The amorphous/crystalline transformation takes place in two stages and indistinct regions of temperature.The isothermal crystallization kindi(?)s wasstudied in these two distinct regions of temperature and the crystallizationactivation lnerge is 3.0ev and 1.0ev respectively.
