· Ca4 Sc8 O16

Ca₄Sc₈O₁₆ is a rare-earth-doped calcium oxide ceramic compound belonging to the family of scandium-containing oxides, which are primarily studied as advanced functional ceramics rather than commercial structural materials. This material is largely in the research phase, investigated for potential applications in high-temperature optics, scintillator detectors, and solid-state lighting due to scandium's strong interaction with the crystal lattice and rare-earth luminescence properties. It represents an exploratory material class where compositional tuning of calcium and scandium ratios is used to engineer specific optical and thermal properties not easily achieved in conventional oxides.

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.
