· BaS2

Barium disulfide (BaS₂) is an inorganic ceramic compound belonging to the chalcogenide family, characterized by ionic bonding between barium cations and sulfide anions. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, with applications in optical systems, solid-state chemistry, and emerging semiconductor research where its optical and electronic properties are leveraged.

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.
