· JVASP-42675· Sm2V2O7

Sm₂V₂O₇ is a rare-earth vanadate ceramic compound combining samarium oxide with vanadium pentoxide in a pyrovanadate structure. This material is primarily investigated in research contexts for applications requiring thermal stability and ionic conductivity, particularly within the family of rare-earth vanadates being explored as solid electrolytes and high-temperature structural ceramics. Its notable characteristics stem from the combination of rare-earth and transition metal oxides, which can provide unique electrochemical and thermal properties compared to simpler ceramic alternatives.
