· Na2 K1 Sb1

Na2KSb is an intermetallic semiconductor compound composed of sodium, potassium, and antimony. This material belongs to the family of alkali-metal antimonides and is primarily of research interest rather than established in large-scale industrial production. The compound is investigated for potential applications in thermoelectric devices and solid-state electronics where its semiconducting properties and relatively low density could offer advantages over conventional alternatives, though it remains largely in the experimental stage with limited commercial deployment.

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.
