AN INVESTIGATION OF LITHIUM CONDUCTING BORATE GLASSES IN THE LIGHT OF PREPARATIVE MODE

Lithium borate glasses of four different compositions have been prepared by using Al-mould, Al-blocks, Cu-drum and Twin roller quenching techniques and characterised by XRD and DTA. It is found that the quenching technique has a profound effect on the glass formation and its electrical conductivity. With Cu-drum quenching technique, it has been possible to extend the glass formation up to 70 mol% Li20. This sample exhibited maximum conductivity. A close scrutiny of glasses for 40 ----c- Li2O ^ 50 mol% prepared by Al-blocks quenching technique reveals that, the composition with 42.5 mol% Li20 gave maximum conductivity. This can be clearly understood on the basis of ‘N4’, the fraction of four co-ordinated boron. © 1990, Taylor & Francis Group, LLC. All rights reserved.
