Glass formation and structure of glasses in the ZnO―Bi2O3―WO3―MoO3 system

Glass formation and structure of glasses in the WO3–ZnO–Nd2O3–Al2O3 system

“…Binary WO 3 -Pb 3 O 4 glasses within the concentration range of 5-30 mol% WO 3 have been also reported [6]. In several papers, special attention has been paid to the glass-formation in tungstate systems containing simultaneously and other nontraditional glass formers such as V 2 O 5 , MoO 3 , and Bi 2 O 3 [7][8][9][10][11][12][13][14]. It has been proven that V 2 O 5 is a better glass-former in comparison with MoO 3 and WO 3 while MoO 3 is better than WO 3 .…”

“…Having in mind the above short survey, it can be concluded that WO 3 is an appropriate compound for the solving of general fundamental structural problems concerning the amorphous state and as well as for the preparation of new type of oxide glasses for technology. The present paper is a continuation of our fundamental investigations on the glass formation tendency in complex oxide systems containing high WO 3 content [11][12][13]. The aim is to study the glass forming ability of the compositions rich in WO 3 (60-80 mol%) in the ZnO-WO 3 -Nd 2 O 3 -Al 2 O 3 system and to elucidate the main building units determining the glass network stability (short range order).…”

“…Infrared and Raman spectroscopies were used to reveal the short range order, the type of polyhedra and their transformation with the composition. The assignments of the infrared bands are made in the framework of the local point symmetry approach for inorganic compounds [13,[44][45][46] taking into account the spectral and structural data for WO 3 -containing crystalline and amorphous phases existing in the literature. It is well known that the structure of m-WO 3 consists of corner-sheared distorted WO 6 octahedra [47,48].…”

“…In our previous studies [13,69,70] a model for the non-traditional glass forming systems containing MoO 3 have been proposed. According to this model, the process of structural transformation is realised in different concentration ranges depending on the nature of the other components.…”

“…Verification of the relation between glass formation ability and glass structure is very important for the prediction and design of such materials. In this context, Dimitriev et al [12][13][14], Iordanova et al [15][16][17] and Milanova et al [18,19] intensively conducted a series of investigations concerning glass forming ability and glass structure in binary and ternary systems containing MoO 3 and Bi 2 O 3 .…”
