Preparation, Structural Characterization and Thermal Decomposition Mechanism of Rare Earth Salts of 3-Nitro-1,2,4-Triazol-5-One

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 • nH_2O, 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.
