· JVASP-21363· TiP2O7

Titanium pyrophosphate (TiP₂O₇) is a ceramic compound belonging to the family of metal phosphates, characterized by a pyrophosphate structure where titanium cations are coordinated with phosphate groups. This material is primarily of interest in research and specialized applications where its thermal stability, ionic conductivity, and chemical resistance are advantageous; it has seen investigation in solid-state electrolytes for energy storage, thermal barrier coatings, and as a catalyst support in high-temperature chemical processes. Compared to conventional phosphate ceramics, titanium pyrophosphates offer enhanced mechanical integrity and thermal durability, making them candidates for applications requiring materials stable at elevated temperatures where traditional oxides may degrade.
