**2.3.1 Raw materials and reagents**

Muscovite mica in bulk state was milled for 1 hour and then sieved and was used as the base. SnCl2 (analytical reagent) was used to produce the metal oxide hydrate on mica flakes and the precipitation was performed by the presence of KClO3 (analytical reagent) as the oxidizing agent. Sorbitan mono-oleate (analytical reagent) was used as the non-ionic surfactant. Also, NaOH (chemical reagent) and HCl (chemical reagent) were used for adjustment of pH.
