| Abstract: | A modified citrate precursor method was used to synthesize nanocrystalline Sr_(1-x)Ca_xTiO_3(x=0.1, 0.2, 0.3, 0.4) powders. TG/DTA, XRD and TEM was used to examine the decomposition behaviour of the precursor and the crystalline phase, and morphology and particle size of the powders. The results indicated that single-phase, slight agglomerated and well-crystallized Sr_(1-x)Ca_xTiO_3 nanopowders with particle size around 50 nm could be obtained after calcining at 900 ℃ for 7 h. |
