· JVASP-107804· K2RbSbBr6

K2RbSbBr6 is a halide perovskite ceramic compound combining potassium, rubidium, antimony, and bromine elements. This is an experimental material under active research for optoelectronic and photovoltaic applications, belonging to the broader family of lead-free double perovskites being developed as safer alternatives to traditional lead halide perovskites. Engineers investigating this material are typically focused on next-generation solar cells, radiation detection, or light-emitting devices where toxicity constraints and compositional stability are critical design factors.

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.
