· Li2 O7 Sr1 Ta2

Li2O7Sr1Ta2 is an experimental oxide ceramic compound combining lithium, strontium, and tantalum—materials historically valued for their ionic conductivity, thermal stability, and dielectric properties. This is a research-phase material within the family of complex perovskite and pyrochlore-related oxides, not yet established in high-volume commercial production. Interest in such mixed-metal lithium tantalates centers on potential applications in solid-state ionic transport, energy storage systems, and advanced ceramics where the combined chemistry of the constituent elements offers tunable electrical or thermal performance.

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.
