· Sc2 Au2 O4

Sc₂Au₂O₄ is a mixed-valence oxide semiconductor combining scandium and gold in a structured ceramic compound. This material is primarily of research and development interest rather than established industrial production, with potential applications in optoelectronics, catalysis, and high-temperature devices where the unique combination of rare earth (scandium) and noble metal (gold) properties could offer advantages in thermal stability and electronic characteristics. The material represents an exploratory composition in the broader family of ternary oxides being investigated for next-generation semiconductor and 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.
