· JVASP-129359· KNb

KNb is an intermetallic compound composed of potassium and niobium, representing a rare earth or refractory metal combination with potential applications in advanced materials research. This material falls into the category of experimental/developmental compounds rather than established industrial alloys, and is primarily of interest in research contexts exploring novel intermetallic phases, high-temperature materials, or specialized electronic/catalytic applications where the unique chemistry of potassium-niobium interactions may offer advantages.

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.
