Synthesis and characterization of zinc oxide incorporated iron borate glass-ceramic

Journal of Alloys and Compounds, 2019
Here, zinc oxide (ZnO) incorporated iron borate (Fe3BO6) glass-ceramics have been synthesized using the traditional melt-quenching technique, and the role of ZnO has been investigated.

Different property studies with network improvement of CdO doped alkali borate glass

Journal of Non-Crystalline Solids, 2018
Quaternary alkali borate glass matrix doped with CdO (0, 2, 4, 6, 8, 10 mol%) have been prepared by using conventional melting and quenching technique.

The structure of borate glass

Glass and Ceramics, 2008
The existing hypotheses on the structure of alkali borate glass were comprehensively analyzed. Their imperfection in explaining the dependences of the properties of the glasses on their composition was noted. Alternative schemes of structural borate complexes which more convincingly explain the characteristics of the change in the properties of this ...

Gradient index in borate glasses

SPIE Proceedings, 1994
ABSTRACTA number of aluminum—borate glasses has been developed for producing gradient index glasses by exchang-ing. Both positive and negative axial grandient were fabracated in the glasses by exchange of Li+ for Na+ and Na+ for Li , respectively. Index change to 0.

Structural models for borate glasses

Journal of Non-Crystalline Solids, 1985
Abstract Neither the Levedev crystalline model nor the Warren and Zachariasen random network model is appropriate for borate glasses. But Jan Krogh-Moe, perhaps building on the ideas of G. Hagg which were disputed by Zachariasen, suggested that borate glasses should contain the larger structural groupings (boroxol, diborate, metaborate, etc.) that ...

Color centers in borate glasses

Vetro e Silicati, 1966
The color centers of the alkali borate glasses are discussed in terms of structural units. The radiation-induced color centers in these glasses are studied by means of optical absorption and E.S.R. The absorption bands of the 2 types of spectra are correlated to the various types of structural units present in these glasses and a no.
