· Sr0.9Y0.1TiO3

Sr₀.₉Y₀.₁TiO₃ is a doped perovskite ceramic compound in which strontium titanate is partially substituted with yttrium, creating a modified oxide structure. This material is primarily of research interest for solid-state energy applications, particularly as a ceramic electrolyte or electrode material in high-temperature electrochemical devices such as solid oxide fuel cells (SOFCs) and oxygen transport membranes, where the doping strategy is engineered to enhance ionic conductivity and chemical stability. The yttrium-strontium substitution is chosen to improve performance over pure strontium titanate by modifying defect chemistry and reducing sintering temperatures, making it attractive for developers seeking cost-effective ceramic electrolyte materials operating in intermediate-temperature ranges.

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.
