· LaSi

Lanthanum silicide (LaSi₂) is an intermetallic ceramic compound belonging to the rare-earth silicide family, characterized by a hexagonal crystal structure and metallic-ceramic hybrid properties. It is primarily investigated for high-temperature structural applications and electronic devices, where its combination of thermal stability and electrical conductivity offers advantages over purely ceramic alternatives; industrial adoption remains limited, with most development occurring in aerospace, semiconductors, and thermal management research contexts.

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.
