Iron sulfide, Pieces, 99.99%, 3 -6 mm

Iron disulfide is utilized as a high-energy density cathode material in primary lithium-iron disulfide (Li-FeS2) batteries, offering a high theoretical capacity and stable discharge voltage.

Iron disulfide targets are used in sputtering processes to deposit thin films for photovoltaic research and the development of next-generation solar absorber layers.
