Pyrite feem ntau yog hais txog pyrite, nws lub ntsiab yog ferrous disulfide (FeS₂).
Hauv qhov xwm txheej, cov qauv siv lead ua ntawm pyrite suav nrog cov qauv cubic thiab octahedral. Nws feem ntau nthuav tawm lub teeb tooj dag xim nrog lub ci xim hlau ci.
Cov hlau nyob rau hauv ferrous disulfide muaj ib tug valence ntawm +2, thaum lub sulfur muaj ib tug valence ntawm -1. Industrially, pyrite yog ib qho tseem ceeb raw khoom rau zus tau tej cov sulfuric acid. Roasting pyrite hauv huab cua ua rau cov tshuaj tiv thaiv 4FeS₂ + 11O₂ (siab kub)=2Fe₂O₃ + 8SO₂. Lub resulting sulfur dioxide yog ntxiv oxidized rau sulfur trioxide, uas ces reacts nrog dej los tsim sulfuric acid. Pyrite kuj tseem siv tau los ua cov khoom siv raw rau cov tshuaj sulfur extraction, nrog rau kev siv dav hauv kev lag luam tshuaj.
