· YCuO2

YCuO2 is a copper-yttrium oxide ceramic compound belonging to the family of mixed-valence metal oxides with semiconductor properties. This material is primarily investigated in research settings for applications requiring oxygen-ion conductivity and thermal stability, particularly as a candidate electrolyte or electrode material in solid-oxide fuel cells (SOFCs) and related electrochemical devices. YCuO2 is notable for its potential to operate at intermediate temperatures while maintaining structural integrity, offering an alternative pathway to conventional yttria-stabilized zirconia (YSZ) in energy conversion systems where cost and material availability are considerations.

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.
