Abstract As a part of an effort to optimize the performance of the ceramic phase shifters, various composites of barium strontium titanium oxide (Ba1-xSrxTiO3; BSTO; 0≤x≤combined with other nonelectrically active oxide ceramics have been formulated which possess low loss tangents and have high tunabilities. To further engineer the electronic properties of the materials, we have studied the effect of ball-milling on the powder characteristics of Ba0.6Sr0.4TiO3/MgO[1] composite ceramics. The effect of the reduction of the overall particle size of the materials from ball-milling is dependent on the additive oxide content; for samples with oxide content > 5.0 wt%, the dielectric constant, and tunability (%) are decreased.Additionally, the materials have been characterized using FTIR, FT-Raman spectroscopy, x-ray diffraction, and grain size analysis has been performed.
