· JVASP-24306· Ba5Ta2Cl2O9

Ba5Ta2Cl2O9 is an oxychloride ceramic compound combining barium, tantalum, chlorine, and oxygen—a mixed-anion ceramic that blends properties of both oxide and halide systems. This is a research-phase material rather than an established commercial ceramic; compounds in this family are investigated for their potential in high-temperature applications, electrical ceramics, and specialized optical or photocatalytic devices where the unique anion chemistry may offer performance advantages over conventional oxides.

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.
