· JVASP-155174· K2SnCl4

K2SnCl4 (potassium tin tetrachloride) is an inorganic ceramic compound belonging to the halide perovskite family, characterized by its layered crystalline structure. This material is primarily studied in research contexts for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in perovskite-based solar cells and light-emitting devices. Engineers consider this compound when designing environmentally benign semiconductor systems where tin-based halides offer both reduced toxicity compared to lead analogues and tunable electronic properties for next-generation energy conversion and display technologies.

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.
