· LaSi2

Lanthanum disilicide (LaSi2) is an intermetallic semiconductor compound belonging to the rare-earth silicide family, characterized by a hexagonal crystal structure. It is primarily investigated as a high-temperature material for thermoelectric applications and as a precursor in the synthesis of rare-earth silicide composites, though it remains largely in the research and development phase rather than mainstream industrial production. Engineers would consider LaSi2 for specialized high-temperature environments where its thermal and electrical properties offer advantages over conventional semiconductors, particularly in thermopower generation and specialized refractory applications.

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.
