, et al.. Formation and properties of chalcogenide glasses based on GeS2-Sb2S3-AgI system. Materials Letters, Elsevier, 2014, 132, pp.203-205. 10 AbstractNovel glasses in GeS 2 -Sb 2 S 3 -AgI system have been prepared by melt-quenching method. A large glass-forming region was found in the novel system, in which almost 60mol% AgI has been incorporated.The basic physiochemical properties of glass samples were investigated. With the addition of AgI, red shift of short-wavelength absorption edge indicates and distinct drop of the glass transition temperature (T g ) were observed. In addition, a high Ag + ion conductivity of 6.37 10 -4 S/cm at room temperature can be obtained in 55(0.6GeS 2 -0.4Sb 2 S 3 )-45AgI sample, indicating that these glasses have potential application as amorphous solid electrolytes.

“…Similar to As-S binary alloys, Ag-containing arsenic sulphides show a very good glass-forming ability over a wide concentration range [1]. Depending on the composition, the glasses produced by quenching As-S-Ag melts in air are either homogeneous or inhomogeneous [1,[9][10][11][12]. The micro-phase separation in the As-S-Ag glasses is due to the liquid-liquid immiscibility in the As-Ag-S ternary system [13,14].…”

“…Recently [4,7,11,12] attention has also been paid to the chalcogenide glasses along the AsS 2 -Ag line, which goes through the miscibility gap. It was established that the electrical conductivity of the glasses increases significantly with increasing Ag concentration and the Ag + ions are the main charge carriers.…”

As 0.33 S 0.67 ) 100-x Ag x (0 ≤ x ≤ 28) bulk glasses showing micro-phase separation in a wide concentration range have been studied by X-ray diffraction, neutron diffraction and extended X-ray absorption fine structure measurements. The AsAgS 2 composition, which forms a homogeneous glass, is modeled with the reverse Monte-Carlo simulation technique. It is established that Ag prefers the environment of S; Ag-As bonding cannot be observed. Similarly to the AsAgS 2 crystalline modifications smithite and trechmannite, the main structural units of the glass are AsS 3 pyramids. The covalent network of As and S atoms becomes fragmented in the glassy AsAgS 2 unlike in the glassy AsS 2 . The environment of Ag atoms in the AsAgS 2 glass differs from that in the crystalline state. In average, each Ag atom has four nearest neighbors, three of them being S and one being Ag.

The purpose of this study is to develop epoxy composites with improved mechanical, thermal, and electrical properties. Semiconducting glass (SG) binary systems such as As 2 S 3 -TlS and As 2 Se 3 -TlS were synthesized in various mole ratios (1:1 and 1:3). Electrically conductive DGEBA-type epoxy-SG-filled composites were developed containing 1-15 wt% of fillers and characterized by X-ray diffraction and scanning electron microscopy techniques. As a result, the effects of the type and amount of semiconductive filler on the mechanical, thermal, and electrical properties of commercial epoxy resins (ERs) were examined. It was found that I 2 doping of the filler significantly increased the electrical conductivity of the composites up to 10 23 S cm 21 . Percolation concentrations were found to be 7 wt% for all composites studied. The maximum tensile strength changed in the range of 86-114 MPa was obtained with 5-10 wt% of SG particles. In addition, the thermal behavior and stability of the epoxy composites were studied using thermogravimetric analysis. The incorporation of SG particles increased the 10% decomposition temperature of neat epoxy by 58C-358C. ER/SG coatings showed the best adhesion results and perfect resistance to 3% NaCl, 3% HCl, and 5% NaOH solutions. POLYM. COMPOS., 39:681-690, 2018.
