· JVASP-11793· K2Mn2O3

K2Mn2O3 is a potassium-manganese oxide ceramic compound belonging to the mixed-metal oxide family. This material is primarily of research interest rather than established in high-volume production, with potential applications in electrochemistry and thermal management due to its manganese oxide backbone. The compound represents an experimental composition that may be investigated for solid-state battery electrolytes, catalytic supports, or high-temperature ceramic coatings where manganese oxides are known to offer redox activity and thermal stability.

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.
