In reactions with aspects of lesser electronegativity, it reacts as an oxidant and varieties sulfides, exactly where it's got oxidation state −2.
Sulfur candles of virtually pure sulfur had been burned to fumigate structures and wine barrels, but at the moment are viewed as way too toxic for residences. Pharmaceuticals[edit]
Zinc sulfide can also be utilised being an infrared optical material, transmitting from noticeable wavelengths to only around twelve micrometers. It can be utilized planar as an optical window or shaped into a lens. It can be made as microcrystalline sheets through the synthesis from hydrogen sulfide gasoline and zinc vapour, which is marketed as FLIR-quality (Forward Wanting Infrared), where the zinc sulfide is inside a milky-yellow, opaque type.
