· Sr0.5Ta1O3

Sr₀.₅Ta₁O₃ is a mixed-valence perovskite oxide semiconductor composed of strontium, tantalum, and oxygen in a defined stoichiometry. This is a research-phase compound studied primarily for photocatalytic and electrochemical applications, particularly in the context of water splitting, environmental remediation, and energy conversion where layered perovskites with partial A-site occupancy offer tunable band gaps and enhanced charge separation. Compared to fully-occupied perovskites (like SrTiO₃), strontium-deficient tantalate compositions target improved visible-light absorption and reduced charge recombination, making them candidates for next-generation photocatalytic systems, though commercial deployment remains limited and material is typically synthesized at laboratory scale.

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.
