Hais txog lub cev lub cev, nws yog xim hlau manganese yog greyish - hlau dawb uas yog tawv thiab nkig, nrog rau qhov ceev ntawm 7.44 g / cm³, melting point ntawm 1244℃, thiab boiling point ntawm 1962℃. Qhov kev sib xyaw ua ke ntawm hardness thiab brittleness ua rau cov hlau manganese nyuaj rau kev ua haujlwm ntawm chav tsev kub, tab sis kuj muab nws qhov tshwj xeeb zoo hauv cov ntawv thov tshwj xeeb.
Chemically, manganese yog heev reactive. Nws oxidizes yooj yim hauv huab cua thiab reacts nrog dilute acids kom tso hydrogen gas. Nws tseem tuaj yeem tsim cov alloys nrog ntau cov hlau, ib qho cuab yeej uas ua rau nws siv dav hauv kev lag luam xws li kev tsim steel.
Hauv cov ntawv thov kev lag luam, manganese tuav txoj haujlwm irreplaceable. Hauv kev tsim cov hlau, manganese yog ib qho tseem ceeb alloying keeb. Nws txhim khu lub zog, hardness, hnav tsis kam, thiab corrosion kuj ntawm steel. Piv txwv li, thaum tsim high-lub zog alloy steel, ntxiv qhov tsim nyog ntawm manganese tuaj yeem txhim kho kev ua tau zoo ntawm cov hlau, ua rau nws tsim nyog rau kev siv hauv kev txuas hniav, kev tsim kho, kev tsim khoom, thiab ntau lwm yam. Tsis tas li ntawd, manganese muaj cov ntawv thov tseem ceeb hauv cov hlau tsis yog -ferrous hlau alloys. Piv txwv li, ntxiv manganese rau aluminium alloys tuaj yeem txhim kho cov alloy lub zog thiab corrosion kuj, ua rau nws siv dav hauv aerospace, automotive manufacturing, thiab lwm yam lag luam.
Los ntawm kev xav ntawm kev lag luam roj teeb, manganese kuj yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev tsim roj teeb. Lithium manganese oxide yog cov khoom siv cathode rau lithium- ion roj teeb, muab qhov zoo xws li tus nqi qis thiab kev nyab xeeb zoo, thiab siv dav hauv cov cuab yeej hluav taws xob, cov khoom siv hluav taws xob me me, thiab lwm yam.
Hauv kev lag luam nyiaj txiag, tus nqi hloov pauv ntawm cov hlau manganese cuam tshuam los ntawm ntau yam. Kev xa khoom thiab kev xav tau zoo yog qhov tseem ceeb cuam tshuam rau tus nqi manganese. Thaum kev lag luam thoob ntiaj teb kev loj hlob ua rau muaj kev xav tau ntau ntxiv rau cov hlau thiab cov hlau tsis yog -ferrous hlau, nws ua rau muaj kev xav tau ntawm manganese, yog li thawb tus nqi manganese; conversely, qhov poob ntawm kev thov yuav ua rau poob ntawm manganese nqi. Tsis tas li ntawd, cov nqi tsim khoom, cov cai thiab cov kev cai, thiab thoob ntiaj teb kev nom kev tswv thiab kev lag luam kuj cuam tshuam rau cov nqi manganese. Cov neeg lag luam tuaj yeem saib xyuas manganese kev lag luam tiam sis thiab koom nrog kev lag luam yav tom ntej lossis nqis peev hauv manganese mining tuam txhab cov khoom lag luam kom ua tiav cov peev nyiaj rov qab.
Hauv cov ntsiab lus, manganese hlau plays lub luag haujlwm tseem ceeb hauv kev lag luam vim nws lub cev thiab tshuaj lom neeg tshwj xeeb, thaum nws cov nqi hloov pauv kuj nthuav tawm cov peev txheej hauv kev lag luam nyiaj txiag. Kev nkag siab txog cov yam ntxwv ntawm cov hlau manganese thiab nws txoj haujlwm hauv kev lag luam nyiaj txiag yog qhov tseem ceeb rau cov kws tshaj lij thiab cov tub ua lag luam hauv kev lag luam ntsig txog.
