· JVASP-102637· YbMgGa4

YbMgGa4 is an intermetallic ceramic compound combining ytterbium, magnesium, and gallium, representing a complex ternary phase within the rare-earth–alkaline-earth–group-13 material family. This compound is primarily of research and exploratory interest rather than established industrial production, with potential applications in high-temperature structural ceramics, electronic substrates, or functional materials where rare-earth chemistry offers advantages in thermal stability or electromagnetic properties. The material's relatively high density and multi-component composition make it a candidate for specialized aerospace, thermal management, or semiconductor applications where conventional ceramics are insufficient.

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.
