· JVASP-37916· BaSr3O4

BaSr₃O₄ is a mixed barium-strontium oxide ceramic compound belonging to the family of alkaline earth oxides, which are known for their refractory and electrochemical properties. This material is primarily explored in research contexts for applications requiring high-temperature stability and ionic conductivity, particularly in solid oxide fuel cells (SOFCs) and oxygen-ion conducting electrolytes. Engineers select barium-strontium oxide systems over single-component alternatives when the tailored ionic transport properties and thermal expansion matching of mixed-metal oxides are critical to device longevity and electrochemical performance.
