New kinetic model for competitive crystallization: Analysis and application

Original language description

Understanding nucleation and crystal growth in undercooled liquids is crucial in the glass and glass-ceramic industry. We developed a new kinetic model for competitive crystallization involving surface layer growth and internal volume nuclei growth. This model allows the separate determination of crystal growth rate and nucleation density. The crystal growth rate is calculated from the extrapolated beginning of the isothermal DSC curve using crystallization enthalpy and mean powder grain radius. A unique method was developed to determine nucleation process parameters using the master plot of the y-function, applicable to both isothermal and non-isothermal DSC data. Verification with Se70Te30 powder showed excellent agreement with experimental data, matching previously published crystal growth rates. For the first time, we determined the nucleation rate and time lag at 60 degrees C for this glass composition. Introduced methods are straightforward, effective, and applicable to glassy materials with similar crystallization behavior.
