Abstract
Borate glasses are the technologically important class of glasses and play a significant role in various applications. Borate glasses contain planar BO3groups as structural units, rather than tetrahedral SiO4groups. The oxygen atoms are, as in SiO2, again connected to two network-forming atoms, in case of boron. The radial distribution analysis describes the B2O3glass structure as consisting of boroxol rings, that is, planar rings containing three boron atoms and three oxygen atoms. The network forming of the B2O3and the SiO4is affected with the addition of some metal cation additives Pb, Zn, Cd, and so forth. These additives also work as a network modifier and a nucleating agent for crystallization of glass. Therefore, the optical properties of the borate glasses have been changed significantly.
Highlights
Glasses are supercooled liquids, transparent, and amorphous in nature
We have discussed the infrared spectroscopy of borate glasses and the effects of various additives on structural properties of these glasses
The borate glasses contain the molecular water, hydroxyl group along with hydrogen bonding which was confirmed by absorption bands in wavenumber range of 2700–3750 cm−1 in the Infrared spectroscopy (IR)
Summary
Transparent, and amorphous in nature. They are inorganic product of fusion which has cooled to a rigid condition without any crystallization. The main distinction between glass and crystals is the presence of long-range order in the crystal structure [1]. The optimization of such properties as a function of composition and other processing parameters requires a good knowledge of the microscopic glassy structure. The method of repeated occurrence is followed in analysing the IR spectrum of solid materials [9, 10] In this spectroscopy, the nature of the light matter interaction is not same as in Raman spectroscopy, and the fundamental differences of the two processes determine the selection rules, which control Raman or IR activity of normal mode of vibrations. A widespread set of very different borate glasses with optical, magnetic, superionic conductivity, and other technologically interesting properties are currently produced [24, 25]
