· TeTaO3

TeTaO3 (tellurium tantalate) is a rare-earth oxide ceramic compound combining tellurium and tantalum in a stoichiometric oxide structure. This material remains primarily in research and development contexts rather than widespread industrial production, with interest focused on its potential as a ferroelectric or electro-optic ceramic, or as a specialty optical/photonic material given the optical properties typical of tellurium-containing 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.
