Abstract: Abstract In this study, powder mixtures at atomic ratios suitable for formation of Sr(Ti0.2Y0.2Zr0.2Sn0.2Hf0.2)O3-x were flash sintered at 1000 °C and 40 mA/mm2. X-ray diffraction and energy-dispersive spectroscopy analyses revealed the formation of single-phase oxides after sintering… read more here.
