Abstract

Lithium borosilicate glasses with different chromium, manganese and cobalt contents were prepared and heat treated at 480, 580 and 680° C for 5 h. The magnetic susceptibilities of untreated and heat-treated samples were measured. The magnetic susceptibility was found to increase as the Cr2O3, MnO or CoO content increased. The values for magnetic susceptibility were co-related to the relative proportion of valence states of transition elements. The magnetic susceptibilities were found to have random behaviour with heat-treatment temperatures. Samples containing Cr2O3 showed transformations from diamagnetic to paramagnetic behaviour with the increase in Cr2O3 content, which may be due to the change of chromium ions from the high valence to the low valence state.
