Coated structure on fly ash particles was produced by liquid stirring of colloidal SiO2. Morphological study by means of scanning electron microscope has consent to controlling the present of outer layer by the addition of variable amount of colloidal SiO2. Similar studies on uncoated and coated particles were also done for comparative purposes. The results exhibits that the SiO2 coating on the fly ash particles was successfully produced by liquid stirring method. It is suggested that the low amount of colloidal SiO2 content results more skinny coating on particles.
