Glass structure and transport properties of Li2O containing zinc bismuthate glasses

Study of structure and optical properties of Fe2O3·CaO·Bi2O3 glasses

“…Unconventional novel oxide glasses formed with the network former Bi 2 O 3 have recently been attractive materials of research due to their interesting physical properties leading to many applications [1]. It has been reported that the pure bismuthate glasses can be obtained at high cooling rates [2].…”

Effect of Stepwise Replacement of Non-Oxide to Oxide Group on Structural Properties ofBi2O3·LiF·B2<

“…In addition to these two high-intensity bands, there exists a shoulder absorption at 1295 cm −1 for the samples with Bi 2 O 3 concentration. This shoulder absorption is assigned to the BO 2 F units [29] and also may be due to Bi-O-Bi vibrations of BiO 6 octahedral units [23]. Furthermore the absorption band centered at 1440 cm −1 and 1530 cm −1 in all the samples except x = 0, is due to BO − stretching vibrations of BO 3 units from varied types of borate groups [30].…”

“…The enhancement in the intensity of the band centered at 1210 cm −1 may be due to the formation of more BO 3 units in meta and ortho borate groups with the addition of oxygen containing Bi 2 O 3 molecule in the glass network. The increasing intensity of the band centered at 1370 cm −1 is due to the presence of BiO − units in the samples other than that with x = 0 [23]. In addition to these two high-intensity bands, there exists a shoulder absorption at 1295 cm −1 for the samples with Bi 2 O 3 concentration.…”

“…Intensity of this band increases with increase in Bi 2 O 3 concentration. It may be due to the Bi-O and Bi-O-Bi bonds in BiO 6 octahedra [20,21,[23][24][25].…”

Structural and Physical Properties of ZnO Modified Bismuth Silicate Glasses

“…The glass samples in the system 40SiO 2 · xZnO · (60 − x)Bi 2 O 3 with composition x = 0, 5,10,15,20,25,30,35, and 40 were prepared using analar grade SiO 2 , Bi 2 O 3 , and ZnO chemicals, by conventional melt-quench method. However, the samples with x (ZnO content) higher than 40 had also been tried to synthesize but we could not succeed.…”
