· JVASP-59674· Ba2YCu3O7

Ba₂YCu₃O₇ is a high-temperature superconducting ceramic compound belonging to the yttrium barium copper oxide (YBCO) family, which was the first superconductor discovered to operate above the boiling point of liquid nitrogen (77 K). This material is used in applications requiring zero electrical resistance and strong magnetic field effects, including MRI magnets, power transmission cables, magnetic bearings, and fault current limiters. Engineers select YBCO over other superconductors primarily because its relatively high critical temperature reduces cooling costs compared to niobium-based alternatives that require liquid helium, making it practical for large-scale industrial and medical systems.

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.
