Glass samples of compositions xCuO-(30-x) ZnO-70B2O3 and xMnO2-(30-x) ZnO-
70B2O3 (where x =5 to 10 mol %) are prepared in the glass forming region. FTIR and density
measurements are carried out for these glasses. IR transmission gives valuable information
about the nature of bonds present in the glass matrix. It has been observed that, density of
MnO2-ZnO-B2O3 glasses has greater value. This is observed that the atomic structure changes
more with the incorporation of MnO2.
