· JVASP-46094· Sr5Ta4O15

Sr5Ta4O15 is a complex oxide ceramic composed of strontium and tantalum, belonging to the family of perovskite-related compounds that are typically studied for high-temperature and electronic applications. This material is primarily found in research and development contexts rather than widespread industrial production, with potential applications in solid-state electronics, thermal barrier coatings, and dielectric devices where its tantalum content provides chemical stability and high refractory character. Engineers considering Sr5Ta4O15 would typically be exploring advanced ceramic solutions for extreme-temperature environments or specialized electronic functions where conventional oxides fall short.

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.
