· JVASP-87192· K2Li3FeO4

K2Li3FeO4 is a mixed-metal oxide ceramic compound containing potassium, lithium, and iron in a crystalline structure. This material falls within the family of lithium-iron oxides and is primarily of research interest rather than an established industrial ceramic. Potential applications span energy storage systems (particularly as a cathode or electrolyte component in lithium-ion batteries), solid-state ionic conductors, and high-temperature ceramics, where its mixed-valent iron chemistry and lithium content could offer advantages in ion transport and thermal stability compared to single-oxide alternatives.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
