· JVASP-103717· Hf3ScSi4

Hf3ScSi4 is a ternary intermetallic ceramic compound combining hafnium, scandium, and silicon, belonging to the family of refractory silicides and intermetallics. This material is primarily of research interest for high-temperature structural applications where exceptional thermal stability and chemical resistance are required; it represents an emerging candidate in the development of next-generation ultra-high-temperature ceramics (UHTCs) and composite reinforcement phases, offering potential advantages over conventional carbides and borides in extreme oxidation environments.

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.
