· Sr0.61Ba0.39Nb2O6

Sr0.61Ba0.39Nb2O6 is a mixed-cation niobate ceramic compound belonging to the tungsten bronze family of structured oxides. This material is primarily of research and development interest for its potential as a dielectric or ferroelectric ceramic, with applications in microwave and RF device engineering where its crystal structure and composition enable tailored electrical properties. The dual-cation substitution (strontium and barium on the A-site of the perovskite-derived structure) allows fine-tuning of phase behavior and dielectric response compared to single-cation niobates, making it valuable for designers of specialized capacitors, resonators, and other functional ceramics operating in the microwave frequency range.

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.
