WebRecrystallization Temperature. Often, recrystallization temperature is a term loosely used for various materials without specifying the purity of the material, degree of deformation and time of annealing and so forth which strongly influence the recrystallization temperature. From: Sputtering Materials for VLSI and Thin Film Devices, 2014. Web4 important concepts to consider in the process of recrystallization. solubility: dissolving purified solute in hot solvent to yield solution. saturation: as solvent cools, solution becomes saturated w/ respect to solute. exclusion: as crystal starts to form, impurities (insoluble) are excluded. nucleation: surface (seed crystal) where ...
