Hf3Sc
ceramic· JVASP-99788· Hf3Sc
Hf3Sc is an intermetallic ceramic compound combining hafnium and scandium, belonging to the family of refractory metal compounds. This material is primarily of research interest for applications requiring extreme temperature stability and chemical inertness, as the hafnium-scandium system exhibits excellent high-temperature performance and oxidation resistance. While not yet widely commercialized in mainstream engineering, Hf3Sc and related hafnium-scandium phases are investigated for advanced aerospace, nuclear, and materials science applications where conventional superalloys or oxides become limiting.

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.
