| Summary: | Series of glass based on (80-x)TeO 2-10PbO-10PbCl 2-xYb 2O 3 where 0.0 =: x =: 3.0 has been successfully prepared by melt quenching technique. The amorphous nature of glass has been determined by X-ray diffraction method. Their corrosion behavior was investigated using the FTIR spectroscopy technique on the sample that has been immersed in distilled water and in aqueous solution of pH 4 and pH 9 for 10 days. There were three major absorption peaks around 3600 cm -1, 889 cm -1 and 470 cm -1 has been observed. The intensity of each peak was found to vary with the Yb 3+ content. |
