This work studied protective material consisting of several metal oxide composites (Pb3O4, WO3, SnO2, and Bi2O3)-natural rubber (NR) for X-ray gamma-ray shielding. The were prepared through open milling vulcanization processes further characterized by scanning electron microscope (SEM), diffraction (XRD), rheometry analysis, density gauge. attenuation coefficient the sample was investigated usi...

The influence of separately added 0.3 wt%, CdO, Bi2O3, BeO and SiO2 on the phase formation, microstructure, magnetic transport properties Y1Ba2Cu3O(7-$\delta$) (Y-123 or YBCO) fabricated by conventional solid state reaction method has been analyzed. results reveal a very low solubility limit for bismuth silicon in Y-123 phase, leading to precipitation phases located within intergranular regions...
