· JVASP-103295· PmHf

PmHf is a ceramic compound combining promethium (Pm) and hafnium (Hf), representing a rare-earth hafnate composition in the broader family of refractory oxides and intermetallic ceramics. This material is primarily of research and specialized industrial interest rather than mainstream use, explored for applications requiring high-temperature stability, radiation resistance, and chemical inertness. The Pm-Hf system is notable in nuclear materials research and advanced thermal management contexts where rare-earth compounds offer superior performance at extreme conditions compared to 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.
