· K1 As4 Br1 O6

K₁As₄Br₁O₆ is a mixed-halide arsenic oxide semiconductor compound, representing an emerging class of hybrid inorganic materials that combine alkali metal, pnictogens, halogens, and oxygen in a single crystalline lattice. This is primarily a research-phase material rather than an established industrial compound; it belongs to the family of perovskite-related and post-perovskite semiconductors being explored for optoelectronic and photovoltaic applications where conventional materials face stability or toxicity constraints. The arsenic-bromine-oxygen framework offers potential for tunable bandgap and carrier transport properties, making it of interest in next-generation photovoltaic devices, X-ray detection, or radiation-hard semiconductor applications where chemical diversity at the atomic level enables property engineering beyond conventional single-phase semiconductors.

Quality & Standards

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.
