· KFe2As2

KFe2As2 is an iron-based layered pnictide compound belonging to the 122-family of iron arsenide superconductors. This is a research material studied primarily for its superconducting properties at low temperatures, rather than a conventional engineering material in widespread industrial use. The compound represents an important class of materials in condensed matter physics and materials research, where it serves as a model system for understanding unconventional superconductivity mechanisms and magnetic interactions in iron-based systems.

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.
