YClO

ceramic

· YClO

YClO is an yttrium-based oxyhalide ceramic compound that belongs to the rare-earth halide family. While primarily a research material rather than an established commercial ceramic, yttrium oxyhalides show promise in applications requiring high thermal stability and chemical inertness, with potential use in specialized optical, electronic, or refractory contexts where rare-earth chemistry provides functional advantages over conventional oxides.

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.
