Several methods can be used to achieve nano crystallization, including:
Sol-Gel Method: This involves the transition of a solution system from a liquid "sol" (mostly colloidal) into a solid "gel" phase. Hydrothermal Synthesis: This method uses high temperature and pressure conditions to crystallize substances from aqueous solutions. Chemical Vapor Deposition (CVD): A process where gas-phase chemicals react to form a solid material on a substrate. Microwave-Assisted Synthesis: Utilizes microwave radiation to heat reactions uniformly and quickly, leading to rapid crystallization.
