“…Thus the presence of tungsten ions in different structural groups and oxidation states in the glass matrix at a given temperature depends on the quantitative properties of modifiers, glass formers, mobility of the modifier cation, etc. [6][7][8]. On the other hand, glasses containing two glass-forming oxides, such as the bismuth germanate glasses, which have superior properties, have a wide range of practical applications [7][8][9].…”

These glasses are attractive to researchers because of their unique structural characteristics, which result from coordination changes in bismuth and germanium.…”

“…14,15 Glasses containing more than one network former is interesting from scientific as well as technological point of view to understand the influence of the simultaneous presence of different network formers on microscopic and macroscopic glass properties such as glass structure, thermal property, dielectric properties, electrical properties etc. [16][17][18][19][20] Glass formation based on the network former SeO 2 and other network formers like TeO 2 , V 2 O 5 , MoO 3 has been reported recently. 14,21,22 It is observed that in Ag 2 O-SeO 2 -B 2 O 3 and Ag 2 O-SeO 2 -MoO 3 glasses the glass formation mainly lies towards SeO 2 end.…”

Structure and dielectric properties of the glasses of compositions yAg 2 O-(1-y)(xSeO 2-(1-x)MoO 3) with varying modifier oxide and glass formers ratio have been reported in this paper. Fourier transform infrared (FTIR) spectroscopy has been employed to investigate the effect of SeO 2 content on the glass network structure. The existence of different characteristic absorption bands corresponding to the vibration of SeO 3 2À anions, isolated MoO 6 units and crystalline molybdate octahedra, has been ascertained from FTIR spectra. It has been observed that the modification of the glass network structure occurs with change of SeO 2 content, which reveals the dual role of SeO 2 as a network modifier and a network former depending on composition. The dielectric constant as well as dielectric strength increases gradually with the increase of SeO 2 content for low modifier oxide content (y), whereas they show a maximum for intermediate and highly modified glasses. The variation of the dielectric parameters correlates directly to the relative proportion of vibration mode of SeO 3 2À ions, which is observed to vary in a similar fashion to dielectric parameters and is, thus in turn, related to the dual behavior of SeO 2 as a modifier and a former depending on composition.

A new Bi-rich part of Bi 2 O 3 -PbO phase diagram was determined using differential thermal analysis and X-ray powder diffraction techniques. Four solid solutions, α-Bi 2 O 3 , γ-Bi 2 O 3 , δ-Bi 2 O 3 and β ss -Bi 8 Pb 5 O 17 , can be distinguished below 37.5 mol % of PbO and one compound, β 2 -Bi 8 Pb 5 O 17 . Two of them, δ-Bi 2 O 3 and β ss -Bi 8 Pb 5 O 17 are high-temperature phases. The large field of γ-Bi 2 O 3 stability was implemented making the crucial difference comparing to phase diagrams from the Bi 2 O 3 -PbO system published so far.
