Structural investigation of Li2O-Bi2O3-B2O3 glasses
Abstract
The structural properties of x Li2O (30-x) Bi2O3-70B2O3; x = 0, 5, 10, 15 & 20 mol %, glasses were investigated by means of FT-IR measurement technique. The IR analysis of the present glass system shows that with increase in lithium oxide content (x≤15 mol%), the frequency bands in the higher region shift towards lower wavenumber, suggest the conversion of BO3 to BO4 structural units, which in turn give rise to the formation of Non Bridging Oxygen's (NBOs). For further increase in lithium oxide content (x>15 mol %), the frequency bands shift towards higher wavenumber indicate the formation of Bridging Oxygen's (BOs).
