Theory/experience correlation of thermochromic perovskite crystallization

Sous titre
The classical Volmer nucleation model (CNT) has been applied to the crystallization of the SmNiO3 phase from its metastable amorphous phase. The correlation between the model, which predicts crystallization rate as a function of annealing temperature, and the experimental results obtained by XRD validated this CNT approach to solid/solid transformation, and enabled us to achieve some thermodynamic and mechanical properties not previously reported.
