· JVASP-57242· Sr2Fe2S2OF2

Sr2Fe2S2OF2 is an oxyfluoride ceramic compound containing strontium, iron, sulfur, oxygen, and fluorine—a mixed-anion ceramic belonging to the family of layered oxychalcogenides. This is a research-stage material studied for its potential in electrochemistry and solid-state ionics, where the combination of oxide and fluoride anions enables tunable ionic conductivity and electronic properties. The material represents an emerging class of mixed-anion ceramics being investigated as candidate materials for solid electrolytes, cathode coatings, or other energy storage applications where conventional oxide ceramics show limitations.
