· JVASP-119093· La3Al4Si6

La₃Al₄Si₆ is a rare-earth alumino-silicate intermetallic compound combining lanthanum with aluminum and silicon. This material is primarily investigated in research and development contexts for high-temperature structural applications, where the rare-earth element provides thermal stability and oxidation resistance. The intermetallic nature offers potential advantages in aerospace and advanced manufacturing settings where lightweight, thermally stable materials are needed, though industrial adoption remains limited compared to more established rare-earth alloys.

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.
