SYNTHESIS AND CHARACTERIZATIONS OF COTIO₃ CLAY NANOCOMPOSITES BY SOL-GEL METHOD

CoTiO₃-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500–800^oC for 2 hours. The presence of rhombohedra phase of CoTiO₃ in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20% (w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration.The optimum condition for nano-composite preparation in 20% (w/w) at 600^oC is obtained.
