· Sr1.6La0.4Nb2O7

Sr1.6La0.4Nb2O7 is a strontium-lanthanum niobate ceramic belonging to the pyrochlore or related layered perovskite family, synthesized as a research compound for advanced thermal and electrochemical applications. This material is investigated primarily in laboratory and prototype settings for solid oxide fuel cells (SOFCs), oxygen ion conductors, and thermal barrier coatings, where its defect chemistry and crystal structure offer potential advantages in intermediate-temperature operation and thermal management. Its development targets next-generation energy conversion systems where traditional zirconia-based ceramics reach performance limits, making it relevant for engineers developing high-efficiency power generation or electrolysis devices in demanding thermal environments.

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.
