摘要：

Hexamethylenetetramine, (CH2)(6)N-4 (HMT) has been employed as a fuel for the first time to synthesize several binary, ternary, and quaternary oxides by the solution combustion method. Technologically important oxides, namely, zirconia, ceria, and their solid solutions, alpha-Al2O3, Cr3+-doped alpha-Al2O3, spinels, MAl2O4 (M = Ca, Mg, Zn and Ni), perovskites, LaMO3 (M = Mn, Cr and Al), La0.67Sr0.33MnO3, and La0.67Ca0.33MnO3, have been synthesized. The oxides synthesized are characterized by X-ray powder diffraction, resistivity, fluorescence spectra, particle size, and surface area measurements. Decomposition of nickel nitrate-HMT complex has been investigated by TG, DTA, TPD, and evolved-gas analysis to elucidate the mechanism.
