· JVASP-97031· LaFeAsO

LaFeAsO is an iron-based layered ceramic compound belonging to the class of iron pnictide superconductors, characterized by alternating layers of LaO and FeAs. This material is primarily a research compound studied for its superconducting properties at relatively high critical temperatures, making it relevant to fundamental condensed matter physics and advanced materials development rather than established commercial applications. Potential engineering interest lies in next-generation superconductor applications where iron-based systems offer advantages over conventional copper-oxide superconductors, including higher upper critical fields and potentially better mechanical stability, though the material remains in the experimental phase for practical device implementation.

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.
