抜粋

Barium strontium titanate ((Ba,Sr)TiO₃) nanosized powders were synthesized via spray pyrolysis of a liquid precursor mist in Ar-O₂ radio frequency induction thermal plasma. To adjust the cation stoichiometry of the complex oxide, liquid precursors were prepared by mixing titanium butoxide (Ti(OBu)₄) stabilized with diethanolamine and aqueous solutions of barium nitrate (Ba(NO₃)₂) and strontium nitrate (Sr(NO₃)₂) stabilized with citric acid. The molar ratios of titanium, barium, and strontium ions (Ba/(Ba+Sr) and (Ba+Sr)/Ti ratios) in the liquid precursor were varied. Pure, high-crystalline (Ba,Sr)TiO₃ (Ba/(Ba+Sr)=0.0-1.0) powders of ∼45 nm in size were synthesized in this one-step process.
