Synthesis and structural investigations of gel metal oxide composites WO3-ZrO2, WO3-TiO2, WO3-ZrO2-SiO2, and their evaluation as materials for the preparation of 188W/188Re generator

► The gel composites of WO3 -TiO2, WO3- ZrO2 and WO3- ZrO2-SiO2 were synthesis using the Complex Sol-Gel Process. ► Their structure was determined with X-ray and neutron scattering methods. ► Gel composite WO3-ZrO2 was selected for construction of 188W/188Re generator
