· Ba2ZrS4

Ba2ZrS4 is a barium zirconium sulfide compound belonging to the ternary metal chalcogenide family, synthesized primarily for research applications rather than established industrial production. This material is of interest in solid-state chemistry and materials science due to its layered crystal structure and moderate mechanical properties, with potential applications in thermoelectric devices, photovoltaic absorbers, and solid-state electrolytes where sulfide-based compounds offer advantages in ionic conductivity or band-gap engineering. The relatively low exfoliation energy suggests this compound may be amenable to mechanical or chemical exfoliation into lower-dimensional forms, making it attractive for exploratory work in 2D materials and heterostructure 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.
