· ScScO3

Scandium oxide (Sc₂O₃) is a rare-earth ceramic compound that functions as a wide-bandgap semiconductor material, often investigated as a component in advanced oxide electronics and photonic devices. Though primarily in research and development rather than high-volume production, Sc₂O₃ is studied for high-temperature applications, transparent electronics, and as a dopant or substrate material in optoelectronic systems where its wide bandgap and thermal stability offer advantages over conventional semiconductors. Engineers consider this material for specialized applications where conventional silicon or gallium nitride alternatives cannot meet extreme temperature, transparency, or radiation-hardness requirements.

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.
