Synthesis and characterization of new materials from the Sb-Ag-Te system — •Trayana Dolchinkova, Vladislava Ivanova, and Yordanka Trifonova — University of Chemical Technology and Metallurgy, Department of Physics, 8 Kl. Ohridski Blvd., 1797 Sofia, Bulgaria

New bulk chalcogenide materials from the Sb-Ag-Te system were synthesized by single-temperature synthesis in a closed volume. The density of the bulk samples was estimated using the pycnometer technique. Some physicochemical properties such as compactness, the molar volume and the free volume percentage of the materials were calculated, and their dependences on composition were determined. XRD analysis was performed to determine the structure and phase composition of the synthesized samples. A scanning electron microscope were used to study the surface morphology and EDS determined the chemical composition of the bulk samples.

Conclusions were drawn based on the results obtained regarding the influence of Ag content on the properties of the bulk samples.
