· JVASP-130763· Ho8Hf

Ho8Hf is a ceramic intermetallic compound composed of holmium and hafnium, belonging to the family of rare-earth hafnide ceramics. This material is primarily investigated in advanced materials research for high-temperature structural applications, where its combination of rare-earth and refractory elements offers potential for extreme thermal environments and oxidation resistance. Ho8Hf represents a compositionally tuned variant within hafnide ceramic systems, with relevance to aerospace thermal protection, nuclear applications, and next-generation refractory coatings where conventional superalloys reach their performance limits.

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.
