· JVASP-97400· K6Na3AlSb4

K6Na3AlSb4 is an intermetallic compound belonging to the alkali metal–aluminum–antimony family, combining potassium, sodium, aluminum, and antimony in a defined stoichiometric ratio. This is an experimental or research-phase material with limited industrial deployment; compounds in this chemical family are primarily investigated for thermoelectric applications, where the combination of light alkali metals and heavy antimony can create favorable phonon-scattering behavior. Engineers would consider such materials only in specialized contexts where tunable thermal and electrical properties offer advantages over conventional thermoelectrics or where the specific alkali-metal doping enables unique phase stability or band structure engineering.

Export Control

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.
