Nanocomposites based on immiscible borate glasses

Synthesis of immiscible borate glasses containing PbO, TeO2 and Fe2O3 was performed by conventional melting technology and by low-temperature sol-gel method. Thermal treatment was performed to obtain glass-crystalline materials. Incorporation techniques were used for the preparation of nanostructured composites based on an amorphous matrix and crystalline powder nanoparticles of PbMoO4 and Fe3O4. Structural characterisation of nanoparticles and nanocomposites was performed by TEM and SAED.
