· JVASP-63949· Ba4YTa

Ba4YTa is a complex oxide ceramic compound containing barium, yttrium, and tantalum, belonging to the family of rare-earth and transition-metal perovskite-related ceramics. This material is primarily investigated in research contexts for high-temperature and electronic applications, where the combination of barium, a rare-earth element (yttrium), and a refractory metal (tantalum) offers potential for enhanced thermal stability, dielectric properties, or ionic conductivity. Ba4YTa and related compounds are of interest in materials science for next-generation functional ceramics, though industrial adoption remains limited compared to more established oxide systems.

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.
