Abstract

Abstract: SrMg_x Ti_1-xO₃ nanocrystalline materials( x =0.1—0.5) were prepared by the stearic acid gel method. Powder samples were characterized by XRD, TG, DAT, IR, XPS and TEM. The results showed that the grain size d changed with the variations of Mg content x , the temperature of calcination and the time of calcination. The result of XPS showed that the binding energy of O 1_s spectra changed with the change of Mg²⁺ content after the replacement of Mg²⁺ for Ti⁴⁺ .

Key words: Stearic acid gel method, SrMg_x Ti_1-xO₃, Nanocrystals, Synthesis
