Abstract
The synthesis, processing, and electrical properties of SrZrO3 and SrTiO3 m aterials have been examined. Phase-pure powders of SrZrO3 and SrTiO3 materi als were synthesized using the Pechini method. Powder processing routes tha t used water and 2-propanol as carrier fluids were developed to achieve hig h green densities, which resulted in sintered densities of > 99% of the the oretical density. The relative permittivity and average breakdown strength for carefully processed SrZrO3 were 60 and 40 V/mum; the corresponding valu es for SrTiO3 were 400 and 35 V/mum. The higher breakdown strengths suggest that these materials can be used in high-voltage capacitor applications.
