· Sc4 In2

Sc₄In₂ is an intermetallic compound composed of scandium and indium, belonging to the family of rare-earth and post-transition metal intermetallics. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with potential applications in semiconductor and optoelectronic device research where the combination of rare-earth and group III metal properties may enable novel band structure or crystal growth characteristics.

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.
