Spherical TiO2/Cr2O3 oxides composites were obtained by template method accompanied with sol-gel method. Ion exchange resins of spherical form (TOKEM-100 and TOKEM-250) were used as an organic polymer matrix. Thermal analysis, X-ray phase analysis and micro-X-ray spectral analysis were used to identify the formation process and compositions of oxides composites. The formation of spherical oxide composite ends at 400 °C and the final products are a mixture of two oxides: Cr2O3 and TiO2 regardless of the structure of the used template. According SEM data prepared TiO2/Cr2O3 composites have spherical form and the size of sphere found to be in a range from 300 to 870 µm

The research was support under the state assignment (no. 10.2281.2017/4.6)
