Coloured glasses in selenite systems

Optical properties of selenite glasses

“…The compositions investigated were selected on the basis of our previous results on the glass formation in various model selenite systems [9][10][11][12]. The constituents were prepared in 15 g batches containing oxides of analysis-grade purity.…”

“…The thermal stability of these glasses increases with the number of the components. In our previous investigations different colored selenite glasses with interesting optical properties were obtained [10,12], which stimulate to continue our study in this direction.…”

“…[1][2][3][4][5][6][7][8]. The main advantage of SeO 2 introducing is its ability to decrease the melting temperature of glass compositions and to modify their optical properties [9][10][11]. The investigations of glass formation in different two-, three and multi-component selenite systems show that it is possible to obtain a selenite glass even at low cooling rate, particularly if the second components are also glass-forming oxides [10].…”

Structural Models of Selenite Glasses Containing Ag⁺ and Cu²⁺ Ions

“…[1][2][3][4][5][6][7]. The main advantage of SeO 2 introducing is its ability to decrease the melting temperature of glass compositions and to modify their optical properties [8][9][10]. The glass formation in different two, three and multicomponent systems containing SeO 2 and other nontraditional glass formers (TeO 2 , V 2 O 5 and MoO 3 ) as well as network modifiers (Ag + , Cu 2+ , Zn 2+ , etc.)…”

“…The glass formation in different two, three and multicomponent systems containing SeO 2 and other nontraditional glass formers (TeO 2 , V 2 O 5 and MoO 3 ) as well as network modifiers (Ag + , Cu 2+ , Zn 2+ , etc.) have been investigated (Table 1) [8][9][10][11][12][13][14][15][16][17][18][19]. Up to now models of structure transformation have been developed in selenite systems with participation of non-traditional network formers (TeO 2 , MoO 3 and V 2 O 5 ) [8][9][10][11] as well glasses containing alkaline modifiers [20].…”
