· JVASP-99680· K2NaTaI6

K2NaTaI6 is a mixed-cation halide perovskite ceramic composed of potassium, sodium, tantalum, and iodine. This is a research-stage compound within the halide perovskite family, which has attracted significant attention for optoelectronic and radiation detection applications due to their tunable bandgap and strong photon absorption. The incorporation of multiple cations (K and Na) and a heavy metal (Ta) suggests this composition is being explored for enhanced stability and radiation shielding performance compared to single-cation perovskites, though practical industrial deployment remains limited.

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.
