är en [[kemisk förening]] av [[järn]] och [[svavel]]. Det förekommer naturligt i mineralerna [[troilit]] och [[magnetkis]], dock inte i [[pyrit]]. Ämnet uppträder ofta i [[Stökiometri#Icke-stökiometriska föreningar|icke-stökiometrisk]] form med verierande halter av järn och svavel.<br /> <br /> ==Egenskaper==<br /> Finkornig järnsulfid kan vara [[Självantändning#Pyrofora ämnen|pyrofor]] i kontakt med luft. Ämnet är [[ferrimagnetisk]]t om det innehåller en övervikt av järn, men närmar sig [[antiferromagnetisk]] ju mer jämvikt det är mellan järn och svavel.<br /> <br /> ==Framställning==<br /> Järnsulfid kan framställas direkt från [[grundämne]]na järn och svavel.<br /> :&lt;math&gt;\rm Fe + S \rightarrow FeS&lt;/math&gt;<br /> <br /> Det kan också produceras av [[Anaerobisk|anaeroba]] [[bakterier]]. Det sker främst i syrefattiga miljöer med lågt [[pH]]-värde.<br /> <br /> ==Användning==<br /> Järnsulfid innehåller för mycket svavel för att vara intressant för utvinning av [[stål]], men om det [[Kalcinering|kalcineras]] frigörs [[svaveldioxid]] som sedan leds genom vatten för att bilda [[svavelsyra]].<br /> <br /> ==Se även==<br /> * [[Aluminiumsulfid]]<br /> * [[Blysulfid]]<br /> <br /> [[Kategori:Järnföreningar]]<br /> [[Kategori:Sulfider]]<br /> <br /> [[ar:كبريتيد الحديد الثنائي]]<br /> [[bg:Железен сулфид]]<br /> [[cs:Sulfid železnatý]]<br /> [[de:Eisen(II)-sulfid]]<br /> [[en:Iron(II) sulfide]]<br /> [[es:Sulfuro de hierro (II)]]<br /> [[fa:آهن(II) سولفید]]<br /> [[fr:Sulfure de fer(II)]]<br /> [[id:Besi(II) sulfida]]<br /> [[it:Solfuro ferroso]]<br /> [[hu:Vas(II)-szulfid]]<br /> [[nl:IJzer(II)sulfide]]<br /> [[ja:硫化鉄(II)]]<br /> [[no:Jernsulfid]]<br /> [[pl:Siarczek żelaza(II)]]<br /> [[pt:Sulfeto de ferro (II)]]<br /> [[ru:Сульфид железа(II)]]<br /> [[sr:Gvožđe(II) sulfid]]<br /> [[zh:硫化亚铁]]</div> Dan Olsson
