Iron phosphate (FePO4) is an inorganic ceramic compound with potential applications in battery technology, catalysis, and advanced materials research. Structurally related to phosphate ceramics, FePO4 is primarily investigated as a cathode material for lithium-ion batteries and as a host framework for ion-exchange applications, where its rigid crystal structure provides stability during electrochemical cycling. While not yet widely deployed in high-volume manufacturing compared to conventional lithium iron phosphate (LiFePO4), FePO4 continues to attract research interest for niche applications requiring chemical stability, thermal resilience, or specific ionic conductivity characteristics.
