· JVASP-102268· K2RbTaBr6

K2RbTaBr6 is a hybrid halide perovskite ceramic compound combining potassium, rubidium, tantalum, and bromine elements. This material is primarily a research-phase compound investigated for optoelectronic and photonic applications, particularly in next-generation semiconductors and radiation detection where the heavy metal (tantalum) and halide framework provide tunable electronic properties and strong photon interaction. While not yet commercially deployed at scale, this material family is notable for offering an alternative to lead-based perovskites with potentially improved stability and reduced toxicity, making it of interest to developers seeking environmentally compliant high-performance optical and electronic devices.

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.
