The effects of gamma irradiation on non-isothermal crystallization kinetics and microhardness of the Li_2O-Al_2O_3-SiO _2 glass-ceramic

摘要

The effects of gamma irradiation on crystallization kinetics and microhardness properties of the Li_2O-Al_2O _3-SiO_2 (LAS) glass-ceramic sample have been investigated. The glass-ceramic was irradiated to γ-source ~(60)Co of 0.7 MGy. The crystallization kinetics of the irradiated and non-irradiated samples were characterized using differential scanning calorimetry. The crystallization kinetics and microhardness properties of the glass-ceramic changed the gamma irradiation, and the high dose of gamma irradiation affects significantly the crystallization kinetics and microhardness properties of the Li _2O-Al_2O_3-SiO_2 glass-ceramic sample.
