摘　　要：Eleven rare earth salts of 3-nitro-1, 2 , 4-triazol-5-one (NTO) was prepared by using aqueous solutions of lithium salt of NTO and corresponding rare earth nitrates. 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.Eleven rare earth salts of 3-nitro-1, 2 , 4-triazol-5-one (NTO) was prepared by using aqueous solutions of lithium salt of NTO and corresponding rare earth nitrates.
