· JVASP-34368· Ca2Ru2O7

Ca₂Ru₂O₇ is a pyrochlore-structured ceramic oxide composed of calcium, ruthenium, and oxygen, representing a mixed-metal ceramic compound typically studied for its electronic and thermal properties. This material remains primarily in research and development phases, investigated for potential applications in high-temperature environments and electrochemical systems where ruthenate ceramics show promise as catalysts, electrical conductors, or structural components. Its notable characteristic is the pyrochlore crystal structure, which provides interesting thermal stability and electronic behavior compared to simpler binary oxides, making it of particular interest in materials science for next-generation energy and catalytic applications.
