Abstract: To analyze Ba,Ti constituents of BaTiO3 nano-crystal prepared by the sol-gel method,Coordinate titration analysis,precipitation gravimetry and X-ray fluorescence,were introduced to determine the mattev quantity ratio of Ba and Ti.The result was 1.011,1.039 and 1.023,respectively.The three ways respectively have the characteristic.Thus,the question of analyzing Ba,Ti constituents in BaTiO3 nano-material is resolved.

Key words: BaTiO3 nano-crystal, coordinate titration analysis, precipitation gravimetry, X-ray fluorescence, chemical composition
