· JVASP-123207· Er3Hf

Er3Hf is a rare-earth hafnium ceramic compound combining erbium and hafnium oxides, belonging to the family of advanced refractory ceramics. This material is primarily of research and development interest for ultra-high-temperature applications where exceptional thermal stability and resistance to oxidation are critical, with potential applications in aerospace propulsion systems, nuclear reactor components, and thermal barrier coatings that must withstand extreme environments beyond the capability of conventional ceramics.

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.
