· JVASP-119706· Fe4As2O11

Fe4As2O11 is an iron arsenate ceramic compound belonging to the mixed-valence iron oxide family. While not widely documented in commercial applications, iron arsenates are primarily of scientific and environmental interest as potential materials for arsenic immobilization and stabilization in waste treatment processes, or as research compounds in solid-state chemistry exploring iron-arsenic oxide phases. Engineers would encounter this material in specialized contexts such as hazardous waste remediation, environmental ceramics development, or fundamental materials research rather than as a conventional structural or functional ceramic.
