Colloidal sol-gel: A powerful low-temperature aqueous synthesis route of nanosized powders and suspensions

The colloidal sol-gel is a well-established method for the synthesis of nanoparticles with high reproducibility, homogeneity and low cost. It is a versatile route which allows synthesising many ceramic materials at the nanometric scale. The process starts with the hydrolysis of the metal precursor a...
