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)= 2,01correspond 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.enSb2O3CrystallizationDifferential scanning calorimetricTungstenActivation energyArticle
