Abstract

We have developed a simple and rapid method for the synthesis of a precursor solution used in the production of SBT powders and thin films of the layered-perovskite phase SrBi2Ta2O9 (SBT). Precursor solution preparation takes less than 30 min and involves the generation of two solutions: (a) Bi(O2CMe)3 dissolved in pyridine and (b) Ta(OCH2Me)5 added to Sr(O2CMe)2 and then solubilized by HO2CMe. After stirring separately for 10 min, these solutions are combined, stirred for an additional 10 min, and used without any further modifications. The individual solutions and ternary mixture were studied using a variety of analytical techniques. Films of the layered-perovskite phase were formed at temperatures as low as 700 °C. Ferroelectric testing of SBT films, fired at 750 °C, reveals standard hysteresis loops with no fatigue for up to 4 × 109 cycles.

(a) The crystal of Bi(O2CMe)3(MeIm)3 · MeIm, 1a, was solved in the triclinic space group P1 with unit cell parameters a = 9.371 (2) Å, b = 11.183 (1) Å, c => 14.354 (2) Å, α = 67.79°, β = 89.79°, γ = 83.16°, V = 1381.5 (4) Å3, for Z = 2. R1 = 4.88 and wR2 = 12.72 for 3906 reflections with F 0 > 4.0σ(F 0). (b) In preparation of the final manuscript, another unit cell for 1a was identified in the monolinic space group C2/c with unit cell parameters a = 17.614 (3) Å, b = 9.205 (2) Å, c = 30.946 (5) Å, β = 91.74 (8)°, V = 5014.9 (2) Å3, for Zi> = 8. R1 = 5.53 and wR2 = 12.63 for 3280 reflections with I < 2σ(I).
