· LuCoO3

LuCoO3 is a perovskite oxide ceramic composed of lutetium and cobalt, belonging to the rare-earth transition-metal oxide family. This material is primarily investigated in research contexts for its semiconducting and magnetic properties, with potential applications in catalysis, solid-state electronics, and energy conversion devices where rare-earth cobaltates offer tunable electronic structures and thermal stability. Compared to more common semiconductor oxides, lutetium cobaltate combines the electrochemical activity of cobalt with lutetium's high atomic mass and lanthanide properties, making it of particular interest for next-generation functional ceramics, though industrial adoption remains limited.

Regulatory Screening

Environmental

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.
