· JVASP-136775· YH2O3

Yttrium hydride oxide (YH₂O₃) is an experimental ceramic compound combining yttrium, hydrogen, and oxygen phases, representing a hybrid material system rather than a conventional single-phase oxide. Research interest in this composition centers on potential applications in hydrogen storage, thermal management, and advanced refractory systems where the hydride component may offer unique electronic or thermal transport properties compared to standard yttria (Y₂O₃). While not yet established in mainstream industrial production, yttrium-based hydride oxides are being explored in solid-state hydrogen applications and high-temperature materials research.

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.
