· Ba2 Y1 Cu3 O7

Ba₂Y₁Cu₃O₇ is a high-temperature superconducting ceramic compound, a member of the yttrium barium copper oxide (YBCO) family that exhibits zero electrical resistance below its critical temperature (~92 K). This material is one of the earliest and most commercially significant high-Tc superconductors, enabling practical applications in fields where liquid nitrogen cooling is feasible, and remains central to superconductor research and industrial implementation decades after its discovery.

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.
