On the analysis of non-isothermal thermoanalytic crystallization experiments

Journal of Non-Crystalline Solids, 1991
Certain aspects of the standard description of thermoanalytical crystallization experiments are examined. In particular, the applicability of the assumption of an Arrhenian temperature dependence of the crystallization rate constant, K, is assessed for non-isothermal transformations where the condition of site saturation is satisfied.

Non-isothermal effectiveness factors for crystal growth

Chemical Engineering Science, 1981
Abstract The effectiveness factor for crystal growth is defined as the ratio of the actual growth rate to the rate that would be obtained if conditions in the bulk solution existed at the crystal surface. The heat of crystallization will produce non-isothermal conditions close to the crystal surface and effectiveness factors for this non-isothermal ...

Non-isothermal crystallization of K2O·TiO2·3GeO2 glass

Journal of Thermal Analysis and Calorimetry, 2009
The crystallization of K2O·TiO2·3GeO2 glass under non-isothermal condition was studied. In powdered glass with particle sizes less than 0.15 mm, surface crystallization was dominant and an activation energy of crystal growth of Ea,s=327±50 kJ mol−1 was calculated. In the size range 0.15 to 0.45 mm, both surface and volume crystallization occurred.

Non-isothermal crystallization of disilicate glasses

1979
Study of the crystallization behaviour of some alkali or alcaline earth silicate glasses. The authors have used the Johnson-Mehl-Avrami equation to describe the glass-crystal transformation. They have established a relation between activation energy, E, and a parameter, m, linked to the reaction mechanism and the DTA curves.
