· BaSi2

Barium disilicide (BaSi₂) is an intermetallic semiconductor compound belonging to the alkaline-earth silicide family, characterized by a hexagonal crystal structure. While primarily a research material rather than a widespread commercial product, BaSi₂ has attracted significant attention in photovoltaic and thermoelectric applications due to its narrow bandgap and potential for efficient solar energy conversion. Its potential advantages over conventional semiconductors stem from earth-abundant constituent elements and favorable optical properties for solar spectrum absorption, making it a candidate for next-generation thin-film solar cells and energy harvesting devices, though production and performance optimization remain active areas of investigation.

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.
