· JVASP-99769· Eu2Co2O5

Eu2Co2O5 is a mixed-valence oxide ceramic combining europium and cobalt in a layered perovskite-related structure. This is primarily a research material studied for its electrochemical and magnetic properties rather than an established commercial ceramic. The compound is of interest in energy storage and catalysis research, particularly for oxygen-evolution reactions in water electrolysis and as a potential cathode material in solid-oxide fuel cells, where its mixed-metal composition offers tunable redox activity compared to single-metal 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.
