· JVASP-10481· K2NaAlAs2

K2NaAlAs2 is an intermetallic compound combining potassium, sodium, aluminum, and arsenic elements, belonging to the class of complex metal aluminides and arsenides. This is a research-phase material with limited industrial adoption; compounds in this family are primarily investigated for semiconductor applications, optoelectronic devices, and solid-state physics studies where the specific combination of metallic and semi-metallic character enables unusual electronic properties. Engineers would consider this material only in advanced research contexts where its unique crystal structure and electronic behavior offer advantages over conventional semiconductors or intermetallics for niche applications.

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.
