| 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. |
