چکیده مقاله:

CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°C 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°C is obtained.

Synthesis of zirconium carbide nanoparticles by sol-gel method and determination of powder characteristics

In this study, zirconium carbide nanoparticles were synthesized by the sol-gel method in the alcoholic system. The sol was prepared in a three-component alkoxide-water-alcohol system based on the chemical sol-gel process under acidic conditions and at pH = 5. Zirconium n-propoxide, furfuryl alcohol were used as raw materials. After the hydrolysis process and formation of the gel, the initial po...
