· Ce1 Mg2 Si2

Ce₁Mg₂Si₂ is an intermetallic compound combining cerium, magnesium, and silicon in a defined stoichiometric ratio, belonging to the rare-earth magnesium silicide family of semiconducting materials. This compound is primarily of research and developmental interest rather than established industrial production, with potential applications in thermoelectric energy conversion and high-temperature electronic devices where rare-earth dopants improve performance. The material combines the lightweight character of magnesium-based intermetallics with rare-earth electronic properties, making it relevant to emerging technologies in waste heat recovery and advanced semiconductor applications where conventional silicon or III-V semiconductors reach performance limits.

Export Control

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.
