The formulae of these salts are determined as RE(NTO)3. nH2O, where RE is Y, La, Ce, Pr, Nd, Sm, Eu, Gd,Tb, Dy or Yb, and n is 6, 7, 7, 7, 8, 7, 7, 7, 5, 5 and 6 correspondingly. Their thermal decomposition mechanism was studied by using DSC, TG-DTG and FT-IR techniques under linearly increasing temperature.展开更多
