· JVASP-34148· Ho2Ru2O7

Ho₂Ru₂O₇ is a rare-earth ruthenate ceramic compound belonging to the pyrochlore oxide family, combining holmium and ruthenium in a complex crystal structure. This material is primarily of research interest for applications requiring high-temperature stability, corrosion resistance, and potentially unusual magnetic or thermal properties; it is not yet widely deployed in commercial engineering applications but represents the broader class of complex oxide ceramics being investigated for advanced thermal barrier coatings, catalytic systems, and functional electronic devices.
