Abstract
Compositions of Sr(TixZr1-x)O3 (0≤ x≤1) were prepared by solid state synthesis using the SrTiO3 and SrZrO3 end members obtained from the Pechini method. For the two compositions Sr(Ti0.2Zr0.8)O3 and Sr(Ti0.8Zr0.2)O3, powder processing routes using 2-propanol as a carrier fluid were developed to prepare tape-cast substrates. The sintering cycles were optimized to obtain specimens that were approximately 99% dense. The relative permittivity, dissipation factor, conductivity, and breakdown strength of Sr(TixZr1-x)O3 monolithic capacitors were measured and compared with those of SrTiO3 and SrZrO3. In addition, during breakdown testing, the leakage current as a function of applied voltage was measured.
