· JVASP-129627· ScTa

ScTa is an intermetallic ceramic compound combining scandium and tantalum, representing a high-density refractory ceramic material in the transition metal compound family. This material is primarily of research and development interest for extreme-environment applications where thermal stability, oxidation resistance, and high-temperature strength are critical. ScTa and related scandium-tantalum systems are investigated for aerospace, nuclear, and high-temperature structural applications where conventional ceramics reach their performance limits, though industrial adoption remains limited compared to established alternatives like yttria-stabilized zirconia or alumina-based composites.

Regulatory Screening

Environmental

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.
