· JVASP-100898· K2HgAsI6

K2HgAsI6 is an inorganic ceramic compound containing potassium, mercury, arsenic, and iodine. This is a research-phase material studied primarily in solid-state chemistry and materials science; it is not yet established in mainstream industrial applications. The compound belongs to a family of halide perovskites and related structures of interest for potential optoelectronic, photovoltaic, or radiation detection applications, though toxicity concerns (mercury and arsenic content) and stability challenges present significant barriers to practical deployment compared to lead-free or less toxic alternatives.

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.
