Crystallization in gel
WebThe sol–gel method (SG), based on the hydrolysis and polycondensation of metal salts or metal alkoxide precursors in a solvent, is a cheap and low-temperature technique that allows fine control of the chemical composition of glass-ceramic materials. WebAug 4, 2024 · Crystal Growth and Nucleation in Gel The crystals are though to nucleate in the gel, but form more in solution. As with all crystal growth, a critical size is necessary to form a stable nucleus. Diffusion of the solute leads to crystal growth.
