· O2 K1 Sc1

O2K1Sc1 is an experimental ternary semiconductor compound containing oxygen, potassium, and scandium. This material represents an emerging class of mixed-metal oxide semiconductors being investigated for potential optoelectronic and energy applications, though it remains primarily in research phases without established commercial production. The combination of rare-earth (scandium) and alkali-metal (potassium) constituents suggests potential for tunable electronic properties, making it of interest to researchers exploring alternative semiconductors for photovoltaic, sensing, or catalytic applications.

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.
