· Ba could be completely removed from solution within 1 day of mixing in the form Ba x Sr 1-x SO 4 and no further significant precipitation occurred after 2 days. Total removal efficiencies of Ba + Sr + SO 4 and the proportion of Ba and Sr in Ba x Sr 1-x SO 4 depended upon the Ba/Sr ratio in the initial HFFF.
Barium Strontium Titanate (BST) materials, both in target (bulk) and thin film (6OOA12OOA) form, were characterized using x-ray diffraction (XRD). Film structure as a function of composition, processing parameters and underlying substrate was determined. Differences in the lattice parameter between bulk and sputtered film form were observed, with the …
