| Abstract: | The infrared
absorption spectra of xZnO(40-x)Fe2O3.60B2O3
glasses (x = 0, 10, 15, 20 and 30
mol% of ZnO) have been investigated to find out the role played by zinc on the
structure of these glasses. ZnO was gradually introduced to replace Fe2O3
in the series of zinc doped iron borate glasses containing 60% B2O3.
The structural changes were inferred by monitoring the infrared spectra of
these glasses in the range 200-4000 cm-1 by KBr technique. Very
small change in absorption bands may occur on addition of ZnO impurity in the
series of zinc doped iron borate glasses. No boroxyl ring formation is observed
in the structure of these glasses. Similarly, tetrahedral formation of zinc is
not observed. The absence of absorption band corresponding to a frequency of
806 cm-1 is attributed to the progressive substitution of boroxol
ring by triborate (BO3) and tetraborate (BO4) groups. |
