· JVASP-38493· Hf5Sc

Hf5Sc is an intermetallic ceramic compound combining hafnium and scandium, belonging to the family of refractory ceramics and high-entropy materials. This material is primarily of research and developmental interest rather than established production use, explored for extreme-environment applications where conventional ceramics reach performance limits. The hafnium-scandium system is investigated for its potential to deliver enhanced thermal stability, oxidation resistance, and mechanical properties at very high temperatures, making it relevant to next-generation aerospace and energy applications.

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.
