· K2 Na1 V1 O1 F5

K₂Na₁V₁O₁F₅ is an experimental mixed-cation vanadium fluoroxide compound classified as a semiconductor, combining potassium, sodium, and vanadium in a fluorine-rich lattice. This material belongs to the family of transition metal fluorides and oxyfluorides, which are of research interest for ionic conductivity, electrochemical applications, and solid-state chemistry due to their framework flexibility and potential for tunable electronic properties. While not yet established in mainstream industrial production, vanadium-based compounds of this type are being investigated for energy storage systems, solid electrolyte applications, and advanced ceramics where the combination of mixed-valence cations and fluorine content could enable novel ionic or electronic behavior.

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.
