· Ba10 Ta4 Cl4 O18

Ba₁₀Ta₄Cl₄O₁₈ is an oxyhalide ceramic compound combining barium, tantalum, chlorine, and oxygen in a complex mixed-anion structure. This material is primarily of research and developmental interest rather than established industrial production; it belongs to the broader family of layered oxyhalides and perovskite-derived ceramics that show promise for semiconducting and photonic applications due to their tunable band structures and anisotropic crystal properties.

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.
