· Sc2 O3

Scandium oxide (Sc₂O₃) is a ceramic semiconductor material belonging to the rare-earth oxide family, valued for its wide bandgap and high thermal stability. It is employed in advanced optoelectronic devices, solid-state lasers, and high-temperature electronic applications, where its exceptional refractory properties and optical transparency in the visible and infrared regions provide advantages over conventional semiconductors. The material is also investigated for next-generation gate dielectrics in microelectronics due to its high dielectric constant and chemical stability with silicon.

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.
