Thermal Physical, and Infrared Spectroscopic Studies on Glasses Prepared by Microwave Route.

This paper describes thermal, physical and spectroscopic properties of glasses prepared by a novel micro wave method. These studies exhibited a strong compositional dependent trend and existence of characteristic boro-vanadate groups in these glasses. The scheme of modification of borate and vanadate groups is controlled by Sanderson's electronegativity principle. Analysis of density and glass transition temperatures suggests the presence of characteristic four coordinated borate and diboro - vanadate groups in these glasses. The presence of [BO4/2]- and [B2V2O9]2-) groups are confirmed by Infrared Spectroscopy of investigated glasses. [ABSTRACT FROM AUTHOR]
