ceramic· Sr4.5Nb4.5O15.5
Sr₄.₅Nb₄.₅O₁₅.₅ is a mixed strontium niobate ceramic compound belonging to the family of complex oxide perovskites and related structures. This material is primarily of research interest rather than established in high-volume production, studied for its potential as a solid electrolyte, electrochemical device component, or functional ceramic where the combination of strontium and niobium oxides can provide ionic conductivity or catalytic properties. The material's attraction lies in its layered perovskite-like framework, which is relevant to solid-state ionics and advanced ceramic applications where thermal and chemical stability are required alongside controlled electrical or ionic transport.

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.
