Magnesium Lump Description
Elemental magnesium yog grey-dawb lub teeb hlau, ob feem peb ntawm qhov ntom ntawm aluminium. Magnesium muaj qhov qis tshaj plaws melting (923 K (650 degree)) thiab qis tshaj qhov kub ntawm 1,363 K (1,090 degree) ntawm tag nrho cov alkaline ntiaj teb hlau.
Ntshiab polycrystalline magnesium yog nkig thiab yooj yim tawg ntawm shear bands. Nws dhau los ua ntau yam zoo thaum alloyed nrog me me ntawm lwm cov hlau, xws li 1 feem pua ntawm txhuas. Lub malleability ntawm polycrystalline magnesium kuj tseem tuaj yeem txhim kho tau zoo los ntawm kev txo nws cov nplej loj rau ca. 1 micron los yog tsawg dua.
Ntshiab magnesium tarnishes me ntsis thaum raug huab cua, txawm hais tias, tsis zoo li cov hlau hnyav dua alkaline hauv ntiaj teb, ib puag ncig tsis muaj oxygen yog qhov tsis tsim nyog rau kev khaws cia vim tias magnesium tiv thaiv los ntawm cov txheej nyias ntawm oxide uas tsis zoo thiab tsis yooj yim tshem tawm.
Cov tshuaj tiv thaiv ncaj qha ntawm magnesium nrog cua lossis oxygen ntawm ambient siab cov ntaub ntawv tsuas yog "ib txwm" oxide MgO. Txawm li cas los xij, cov oxide no tuaj yeem ua ke nrog hydrogen peroxide los tsim magnesium peroxide, MgO2, thiab nyob rau ntawm qhov kub thiab txias, peroxide tej zaum yuav ntxiv reacted nrog ozone los tsim magnesium superoxide Mg (O2) 2.
Magnesium reacts nrog dej ntawm chav tsev kub, txawm hais tias nws reacts qeeb qeeb dua li calcium, ib pawg zoo sib xws 2 hlau. Thaum submerged hauv dej, hydrogen npuas tsim maj mam rau saum npoo ntawm cov hlau - tab sis, yog tias hmoov, nws reacts sai dua. Cov tshuaj tiv thaiv tshwm sim sai dua nrog kub dua. Magnesium cov tshuaj tiv thaiv rov qab nrog dej tuaj yeem siv tau los khaws lub zog thiab khiav lub cav siv magnesium. Magnesium kuj reacts exothermically nrog feem ntau cov acids xws li hydrochloric acid (HCl), ua cov hlau chloride thiab hydrogen gas, zoo ib yam li cov tshuaj tiv thaiv HCl nrog txhuas, zinc, thiab ntau lwm yam hlau.
Cov ntawv thov ntawm magnesium suav nrog nws siv los ua deoxidiser rau tooj liab, tooj dag thiab npib tsib xee alloys thiab nws kuj tau ntxiv rau ntau lub hauv paus aluminium alloys. Nws yog lub hauv paus muaj zog, lub teeb alloys siv nyob rau hauv lub dav hlau thiab tsheb industries (xws li nyob rau hauv lub cav sib dhos). Alloys nrog zirconium thiab thorium kuj tau tshawb xyuas rau lawv siv hauv kev tsim dav hlau. Ntshiab magnesium kuj tseem siv tau los ua cov khoom siv hluav taws xob tua hluav taws los tiv thaiv lwm yam hlau.
