Yes, crystallite size can be controlled through various synthesis methods and conditions:
Precipitation and Sol-Gel Methods: These methods allow for control over crystallite size by varying parameters such as pH, temperature, and precursor concentration. Thermal Treatments: Calcination and reduction processes can be optimized to achieve desired crystallite sizes. Use of Stabilizers: Additives such as surfactants or polymers can be used to stabilize small crystallites and prevent agglomeration.
