Abstract :

Stoichiometric tetragonal Bal-xSrxTiO3 (x = 0.23) nanopowders were prepared by stearic acid gel(SAG) method using barium stearate, strontium stearate, tetrabutyl titanate as Ba, Sr, Ti sourcesand stearic acid as complexing reagent. Thermal analysis including differential thermogravimetric(DTG) and TG, Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD) andtransmission electron microscopy (TEM) were used to characterize the crystallization process,particle size and morphology of the calcined powders. The results indicated that single- phasetetragonal and well crystallized Bal-xSrxTiO3 (x = 0.23) nanopowders with particle size around45 nm were formed after calcining the dried gel at 700 °C for 2 h.PACS code: 81,07Wx
