· JVASP-137282· K2Na4Co2O5

K2Na4Co2O5 is a mixed-alkali cobalt oxide ceramic compound combining potassium, sodium, and cobalt in an oxide lattice structure. This is a research-phase material investigated primarily for electrochemical and catalytic applications rather than a widely commercialized engineering ceramic; the cobalt oxide family is known for activity in energy storage, oxygen evolution reactions, and heterogeneous catalysis, making compositions like this relevant to emerging clean energy technologies.

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.
