K2NaInAs2
ceramic· K2NaInAs2
K2NaInAs2 is a ternary ceramic compound belonging to the chalcopyrite family of semiconductors, combining potassium, sodium, indium, and arsenic. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications where compound semiconductors offer band-gap engineering advantages over elemental materials. The mixed-alkali composition and arsenic-based structure position it within emerging thin-film solar cell and infrared detector development, though industrial adoption remains limited compared to established alternatives like GaAs or InAs.

Regulatory Screening
Environmental
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.
