Abstract: The 57Fe Mössbauer technique has been used to investigate the behaviour of glasses and their corresponding glass ceramic derivatives obtained from the system XMnO(40-X)YFe2O3.10Al2O3.50B2O3,  along with the effect of Al and Mn doping at the Fe-site for all the samples. MnO was introduced gradually to replace Fe2O3 in the series such that X=0,5,10,15,20 and 25 mol% of MnO containing 50% B2O3. The structural changes observed are consistent with Mn2O3 formulation and inferred by monitoring the infrared absorption spectra in the range 500-4000cm–1 by KBr technique. The Mössbauer technique is used for identification of crystalline material and the results are compared with that obtained from X-ray diffraction.
