· Ba1 Zr1 O3

BaZrO₃ (barium zirconate) is a perovskite ceramic compound that functions primarily as a proton-conducting electrolyte material in solid-state electrochemical devices. This compound is of significant research interest for intermediate-temperature fuel cells, hydrogen separation membranes, and electrochemical sensors, where its ability to conduct protons at elevated temperatures offers advantages over traditional yttria-stabilized zirconia (YSZ) electrolytes in terms of lower operating temperature and improved performance windows. Engineers select BaZrO₃-based systems when seeking materials that bridge the gap between high-temperature solid oxide fuel cells and lower-temperature polymer electrolyte systems, though the material remains primarily in the development and pilot-scale phase rather than high-volume commercial deployment.

Export Control

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.
