ceramic

· Fe3PO7

Fe3PO7 is an iron phosphate ceramic compound belonging to the family of phosphate-based ceramics, which are inorganic, high-temperature-stable materials formed from iron and phosphate phases. While not a widely commercialized engineering material, iron phosphates have been investigated in research contexts for applications requiring chemical durability, thermal stability, and biocompatibility; this compound and related iron phosphate systems are of particular interest in nuclear waste immobilization, bioactive coatings, and corrosion-resistant ceramic matrices where traditional oxides may be inadequate.
