Abstract

Crystallization kinetic studies of ternary antimonite glasses within the 60 Sb2O3-(40-x) NaPO3-xWO3 system x= (5, 15)
were prepared using the melt quenching technique were performed by non-isothermal methods using differential
scanning calorimetric (DSC) its measurements showed glasses a very stable with the addition of WO3. The kinetic
parameters Ea and n by applying Ozawa and Chen methods were found to be in good agreement with each other the
values of crystallization activation energy were calculated in the range of 49, 30 Kcal.mol-1 (Chen) and 52, 33Kcal.mol-1
(Ozawa) and Avrami constant, nmoy(SN5W)=2.05, nmoy(15W)= 2,01 correspond decreasing nucleation rate. The evolution
of hardness appears increases linearly versus tungsten content in the glasses; the hardness is close from 325 to 425. This
study could open new avenues of research for ternary antimony-based glasses for applications in nonlinear properties.
