Název v původním jazyce

Crystallization kinetics of the Y3Al5O12 glass

Popis výsledku v původním jazyce

Crystallization of glass prepared by flame technique from a crystalline YAG precursor synthesized by Pechini method was studied under noneisothermal conditions by differential scanning calorimetry. The crystallization peaks were mathematically deconvoluted into two peaks representing two overlapping thermal effects. These two peaks were examined in terms of the nucleationegrowth Johnson-Mehl -Avrami model, autocatalytic Sestak - Berggren model and Malek z(alpha) and y(alpha) functions. At lower heating rates, the only process in the system was volume crystallization with the apparent activation energy of 555 +/- 37 kJ* mol(-1).At higher heating rates, partial change of crystallization mechanism was observed with significant contribution of surface crystallization and the activation energy of 606 +/- 31 kJ* mol(-1)
