· JVASP-139285· LaO2

Lanthanum dioxide (LaO₂) is a rare-earth oxide ceramic belonging to the lanthanide oxide family, characterized by high density and stiffness. While primarily of research interest rather than established industrial production, LaO₂ and related rare-earth oxides are investigated for applications requiring thermal stability, chemical inertness, and radiation resistance—particularly in nuclear fuel cycles, high-temperature structural ceramics, and advanced optical/photonic devices where rare-earth dopants provide unique functional properties.

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.
