· JVASP-37650· HoHfOs2

HoHfOs2 is a rare-earth ceramic compound combining holmium, hafnium, and osmium oxides, representing an experimental material within the high-entropy oxide ceramic family. This composition is primarily a research material under investigation for extreme-environment applications where exceptional thermal stability, hardness, and chemical resistance are required; it belongs to an emerging class of ceramics designed to withstand conditions that exceed the performance envelope of conventional refractory oxides.

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.
