FTIR and DTA Investigations on B2O3-CaO-MnO2 Glasses
2018
International Journal for Research in Applied Science and Engineering Technology
Di erent glass samples were prepared in the system 60B 2 O 3 -(40-x) CaO-xMnO 2 (where x=0, 5, 10, 15 and 20 mol %) employing a rapid melt-quenching technique. The effect of MnO 2 content on structure of the glasses are systematically investigated by X-ray diffraction, FTIR and DTA techniques. The amorphous nature of the samples was checked by X-Ray diffractometry. IR measurements revealed an existence of trigonal BO 3 and tetrahedral BO 4 structural units. The glass transition temperature (T g
