dysprosium oxide
1.In this work, spectral fitting matrix projection-Kalman filter method was developed and applied to correction of spectral interferences produced by rare earth matrix peaks with simple shapes in determination of calcium, and it was applied to correct spectral interferences caused by terbium oxide and dysprosium oxide respectively, and satisfactory results were obtained.
2.The decomposition voltages of dysprosium oxide and sodium flride are measured by using the linear sweep voltammetry(with glay)carb as the indicator-electrode). The results are that E~(900℃)=1.34V for Dy_2O_3 and E~(970℃)=2.71V for NaF.
