ceramic

· JVASP-124373· PmHg

PmHg is a ceramic compound combining promethium (a rare radioactive lanthanide) with mercury, representing an experimental material primarily of research interest rather than established industrial production. This compound belongs to the family of intermetallic and rare-earth ceramics, with potential applications in specialized nuclear, thermal, or radiation-based systems where promethium's decay properties might be exploited. The material is notable for its extreme density and the inherent challenges of handling promethium's radioactivity, making it relevant only to highly specialized applications in nuclear technology or advanced materials research rather than mainstream engineering.

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.
