“…An extensive literature survey shows that ball milling has been used to synthesize several ferroelectric and multiferroic materials [6][7][8][9]. However, very few reports are available on the synthesis and extensive characterization of Ba 1-x Sr x TiO 3 via ball milling.…”

In the present study, specimens of composition Ba 1-x Sr x TiO 3 (x = 0.0, 0.05, 0.075, 0.10 & 0.15) were synthesized using mechanochemical activation technique and their structural, dielectric and ferroelectric characteristics were investigated for the major applications such as a multi-layered ceramic capacitor (MLCC) and microwave tunable devices. Structural analysis using X-ray diffraction pattern of the systems by Rietveld refinement confirms the formation of tetragonal phase with P4 mm space group. The intensity ratio of bonds and wave number shift in Raman spectra suggests little structural changes with strontium content. Microstructural investigation reveals that there is no appreciable change in grain size with increasing strontium concentration. The results on the variation of dielectric constant with temperature suggest the shifting of Curie temperature to lower temperature side with increasing strontium concentration. Current-voltage characteristics reveal that with increasing strontium content current increases which can be correlated with the observed variation of activation energy of the studied samples, which also decreases with the increasing concentration of strontium.

“…Conventional solid-state reaction is not suitable for preparing BST powders with high performance. This method has high energy consumed cost and also has a tendency to produce coarse BST powders with larger particle size, wider particle size distribution and higher impurity content due to repetitive calcinations and grinding treatments [5][6][7]. The sol-gel technique is capable of producing nano-sized powders, but most of the starting chemicals are expensive, and producing period is long, sensitive to moisture, and with poorly inhomogeneous compositions in a batch [4,8].…”

Barium strontium titanate nano powders were prepared by mixing ethanol solution of tetrabutyl titanate with an aqueous solution of Ba(OH)2•8H2O and Sr(OH)2•8H2O with a certain molar ratio of barium to strontium at 40°C－95°C. The products were characterized by thermogravimetry (TG), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), transmission electron microscope (TEM) and atomic force microscopy (AFM). The results show that the powders prepared with the reactant concentration of 0.8M are spherical in particle shape with the grain size of 50nm－65nm. When the annealing temperature of the powders is higher than 906°C, the hydroxyl groups existed in barium strontium titanate lattice are removed. XRD analysis demonstrate that the as-prepared powders are cubic phase. All the diffraction peaks are shifted towards higher diffraction angles and the lattice parameter a calculated decreases linearly with serial decrease of the molar ratio of barium to strontium.
