· B2 O8 Ta2

B₂O₈Ta₂ (tantalum borate) is an inorganic ceramic semiconductor compound combining tantalum oxide with boron oxide constituents. This material remains primarily in the research and development phase, with potential applications in high-temperature electronics, optical devices, and specialized dielectric systems where the combination of tantalum's refractory properties and boron's glass-forming characteristics offers thermal stability and electrical functionality. Engineering interest in tantalum borates stems from their potential to operate in extreme environments and their use as precursors or components in advanced ceramic matrix composites, though industrial-scale production and deployment remain limited compared to conventional tantalum oxides or boron nitride ceramics.

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.
