Muaj ob txoj kev tsim khoom rau hlau calcium.Ib qho yog txoj kev electrolytic, uas tsim cov hlau calcium uas muaj purity feem ntau tshaj 98.5%.Tom qab ntxiv sublimation, nws tuaj yeem ncav cuag purity ntau dua 99.5%.Lwm hom yog hlau calcium uas tsim los ntawm aluminothermal txoj kev (tseem hu ua slurry txoj kev), nrog ib tug purity ntawm feem ntau nyob ib ncig ntawm 97%.Tom qab ntxiv sublimation, purity tuaj yeem txhim kho rau qee qhov, tab sis qee qhov impurities xws li magnesium thiab txhuas muaj cov ntsiab lus siab dua li cov hlau electrolytic calcium.
Nyiaj dawb lub teeb hlau.Mos kev ntxhib los mos.Qhov ceev ntawm 1.54 g / cm3.Melting point 839 ± 2 ℃.Kub taw tes 1484 ℃.Kev sib xyaw ua ke valence + 2.Ionization zog yog 6.113 electron volts.Cov khoom siv tshuaj muaj zog thiab tuaj yeem hnov mob nrog dej thiab kua qaub, tsim cov roj hydrogen.Ib txheej ntawm oxide thiab nitride zaj duab xis yuav tsim nyob rau saum npoo ntawm huab cua kom tiv thaiv corrosion ntxiv.Thaum rhuab, yuav luag tag nrho cov hlau oxides yuav txo tau.
Ua ntej, hlau calcium tuaj yeem siv los ua tus neeg sawv cev txo qis hauv kev lag luam metallurgical thiab tshuaj lom neeg.Nws tuaj yeem siv los txo cov hlau oxides thiab halides.Tsis tas li ntawd, hlau calcium kuj tseem siv tau los npaj lwm cov hlau hnyav uas yuav tsum tau muaj hlau, xws li zinc, tooj liab, thiab txhuas.
Thib ob, hlau calcium kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau.Calcium tuaj yeem ntxiv
Txhawm rau txhim kho kev ua tau zoo thiab zoo ntawm cov hlau.Calcium tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau, thaum Txo cov brittleness ntawm hlau.Tsis tas li ntawd, ntxiv calcium tuaj yeem tiv thaiv kev tsim cov oxides thiab impurities hauv steel, Yog li txhim kho cov hlau zoo.
Tsis tas li ntawd, hlau calcium kuj tuaj yeem siv los npaj ntau yam alloys.Calcium tuaj yeem cuam tshuam nrog lwm cov khoom siv hlau Cov khoom sib xyaw ua ke, xws li calcium aluminium alloys, calcium tooj liab alloys, thiab lwm yam. Cov alloys muaj ntau yam tshwj xeeb lub cev thiab nws cov khoom siv tshuaj siv tau los tsim ntau yam ntaub ntawv thiab cov khoom siv hluav taws xob.
Thaum kawg, hlau calcium kuj tuaj yeem siv los npaj ntau yam sib xyaw.Piv txwv li, calcium tuaj yeem cuam tshuam nrog oxidation Elements xws li cov tebchaw thiab sulfides tsim ntau lub tebchaw, xws li calcium oxide thiab calcium sulfide.Cov khoom sib txuas Cov Khoom Siv tau dav siv hauv kev tsim cov khoom siv hauv tsev, chiv, thiab tshuaj.
