Hlau (Fe) yog ib qho kev hloov pauv hlau, paub txog nws lub zog, ductility, thiab reactivity. Nws yog ib qho tseem ceeb tshaj plaws nyob rau hauv lub ntiaj teb lub pob zeb thiab ua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem lom neeg. Nws muaj peev xwm ua tau yooj yim tsim cov ntawv cog lus nrog lwm cov ntsiab lus, suav nrog sulfur, ua rau nws yog ib qho tseem ceeb hauv ntau cov tshuaj tiv thaiv. Iron's reactivity ua rau nws yooj yim rau corrosion, yog ib qho tseem ceeb hauv ntau daim ntawv thov xav tau cov ntaub ntawv ruaj khov. Kev kawm txog hlau cov khoom pab peb nkag siab txog nws txoj kev cuam tshuam nrog leej faj thiab kev tsim cov tom ntej hlau sulfide.

Sulfur: Cov Reactive Nonmetal

Khoom thiab tshwm sim

Sulfur (S) yog nonmetal paub txog nws cov yam ntxwv xim daj thiab nws muaj zog tsw nyob rau hauv nws cov elemental daim ntawv. Ib lub ntsiab lus reactive heev, nws nkag tau nrog ntau lwm cov ntsiab lus, suav nrog hlau, tsim ntau yam sib txuas. Sulfur cov nplua nuj nyob rau hauv cov xwm txheej yog qhov tseem ceeb, thiab nws cov khoom siv tshuaj lom neeg ntau yam ua rau nws siv dav hauv kev lag luam xws li kev tsim cov chiv mus rau vulcanization ntawm roj hmab. Kev nkag siab txog cov sulfur reactivity yog qhov tseem ceeb hauv kev nkag siab tias nws cuam tshuam li cas nrog hlau los tsim hlau sulfide.

Tsim thiab Hom Iron Sulfide

Tshuaj Reactions

Cov tshuaj tiv thaiv ntawm hlau thiab sulfur tsim hlau sulfide (FeS), cov tshuaj sib xyaw nrog ntau hom nyob ntawm cov xwm txheej ntawm cov tshuaj tiv thaiv. Daim ntawv yooj yim tshaj plaws yog hlau (II) sulfide, feem ntau tsim los ntawm cov tshuaj tiv thaiv ncaj qha ntawm hlau thiab sulfur ntawm qhov kub siab. Lwm cov qauv ntawm hlau sulfide, xws li pyrite (FeS₂, tseem hu ua fool's gold), muaj nyob thiab nthuav tawm cov qauv siv lead ua sib txawv thiab cov khoom. Cov tsim ntawm no ntau hom ntawm hlau sulfide yog hnyav heev los ntawm kub, siab, thiab muaj lwm yam ntsiab.

Cov ntawv sib txawv ntawm Iron Sulfide

Feem ntau cov qauv ntawm hlau sulfide suav nrog:

• Hlau (II) sulfide (FeS): Cov khoom dub, crystalline feem ntau tsim los ntawm cov tshuaj tiv thaiv ncaj qha ntawm cov hlau thiab cov sulfur.
• Pyrite (FeS₂): Kuj tseem hu ua hlau disulfide los yog dag tus kub, daj, xim hlau ntxhia nrog cubic siv lead ua qauv.
• Pyrhotite (Fe_{1-x ib}S): Ib qho tsis-stoichiometric hlau sulfide nrog cov ntsiab lus hlau sib txawv, feem ntau nthuav tawm cov khoom sib nqus.
• Mackinawite (FeS): Ib daim ntawv tsis ruaj khov ntawm hlau (II) sulfide, feem ntau tshwm sim ua ntej rau lwm cov hlau sulfide theem.

Kev siv hlau sulfide

Kev Siv Hluav Taws Xob

Ntau yam hlau sulfide Cov tebchaw pom cov ntawv thov hauv ntau qhov kev lag luam: Pyrite, piv txwv li, yog ib qho tseem ceeb ntawm sulfur rau sulfuric acid ntau lawm. Ntau hom hlau sulfide kuj tseem ua lub luag haujlwm hauv metallurgy thiab tsim cov pigments. Kev thov tshwj xeeb ntawm ib qho tshwj xeeb hlau sulfide nyob ntawm nws qhov tshwj xeeb tshuaj thiab lub cev yam ntxwv. Kev tshawb fawb ntxiv rau cov khoom thiab cov tshuaj tiv thaiv ntawm cov tebchaw no txuas ntxiv nthuav dav lawv cov ntawv thov.

Ib puag ncig qhov tseem ceeb

Lub xub ntiag ntawm hlau sulfide nyob rau hauv ib puag ncig tuaj yeem muaj qhov cuam tshuam loj heev. Qee cov ntaub ntawv, xws li pyrite, tuaj yeem ua rau cov kua qaub mine kua thaum raug cua thiab dej. Nkag siab txog kev cuam tshuam ib puag ncig ntawm hlau sulfide yog qhov tseem ceeb rau kev tswj hwm ib puag ncig zoo thiab cov tswv yim kho kom zoo. Ua tib zoo xav txog qhov cuam tshuam ib puag ncig yog qhov tseem ceeb thaum lub sijhawm rho tawm, ua, thiab pov tseg cov ntaub ntawv uas muaj hlau sulfide.
