High Purity Nano Fe Powder for High-Entropy Alloys

Kugwiritsa ntchito chitsulo m'mafakitale ngati zitsulo za kaboni ndizochuluka ndipo zimaposa 410 IRONOther alloys. Zitsulo za carbon ndi ma aloyi achitsulo okhala ndi carbon mosiyanasiyana, nthawi zambiri mpaka 1.7% carbon. Zitsulo zina zimaphatikizidwanso muzitsulo za carbon kuti apange zitsulo zotsika kwambiri. Zitsulo zoterezi nthawi zambiri zimakhala faifi tambala ndi chromium ndipo zimayikidwa ngati chitsulo chosapanga dzimbiri, zitsulo zazitsulo, ndi zitsulo zosagwira kutentha. Zosakaniza zachitsulo zopanda chitsulo monga chitsulo chonyezimira, chitsulo chonyezimira, chitsulo cha nickel ndi silicon iron zilinso ndi ntchito zambiri zofunika. Kugwiritsidwanso ntchito kwina kofunikira kwa chitsulo kumakhala ngati chothandizira mafakitale. Amagwiritsidwa ntchito muzolemba zothandizira mu ndondomeko ya Haber yopangira ammonia, komanso mu ndondomeko ya Fischer-Tropsch yopangira mafuta opangira mafuta. monga otentha haidrojeni jenereta, gel osakaniza propellant, kuyaka activator, chothandizira, madzi kuyeretsa adsorbent, sintered yogwira wothandizila, etc; ntchito mankhwala ufa zitsulo, mitundu yonse ya mbali makina ndi mankhwala zigawo zikuluzikulu, simenti mankhwala carbide, etc; monga kuchepetsa wothandizira komanso kugwiritsidwa ntchito pakupanga mchere wachitsulo ndi mafakitale amagetsi; monga zowonjezera zakudya (zolimbitsa chitsulo), zoponyera, kapena zochepetsera; m'makampani amagetsi, ufa wazitsulo. Iron ndi mchere womwe umagwiritsidwa ntchito polimbitsa chakudya chomwe chimakhala chofunikira popewa kuchepa kwa magazi m'thupi, chomwe chimachepetsa kukhazikika kwa hemoglobini komanso kuchuluka kwa okosijeni kumatenda. Zomwe zimapangidwira zimaphatikizapo ferric ammonium sulfate, chloride, fructose, glycerophosphate, nitrate, phosphate, pyrophosphate, ferrous ammonium sulfate, citrate, sulfate, ndi sodium iron edta. mawonekedwe a ferric (fe3+) ndi chitsulo pamtunda wapamwamba kwambiri wa valence ndipo mawonekedwe a ferrous (fe2+) ndi chitsulo m'munsi mwa valence state. gwero lachitsulo lisasinthe mtundu kapena kuwonjezera kukoma ndipo likhale lokhazikika. ufa wachitsulo umatulutsa mawonekedwe otsika komanso otsika. amagwiritsidwa ntchito kulimbikitsa ufa, zowotcha, pasitala, ndi phala. Kusungunula chitsulo kuchokera ku miyala yake kumachitika mu ng'anjo yoyaka moto momwe mpweya (coke) ndi limestone zimatenthedwa ndi miyala yomwe imapangitsa kuti chitsulo chachitsulocho chichepe ndikusandulika chitsulo chosungunuka, chotchedwa "chitsulo cha nkhumba." Chitsulo cha nkhumba chosungunuka chimakhalabe ndi kaboni ndi silicon komanso zonyansa zina pamene zimasonkhanitsa pansi pa ng'anjoyo ndi slag yosungunuka yoyandama pamwamba pa chitsulo. Onse amakomedwa ndi kukhetsedwa. Njirayi ikhoza kukhala yopitilira chifukwa zowonjezera zowonjezera zimatha kuwonjezeredwa ngati chitsulo ndi slag zimachotsedwa pansi pa ng'anjo.Mtundu uwu wachitsulo suli wothandiza kwambiri pakupanga zinthu, chifukwa ndi wonyezimira komanso wosalimba kwambiri.Mmodzi mwa kupita patsogolo kwakukulu mu ukadaulo wa chitsulo chosungunula chinali chitukuko cha njira ya Bessemer ndi Henry Bessemer (1813-1898). Pochita izi, mpweya woponderezedwa kapena mpweya umakakamizika kupyolera muchitsulo chosungunuka cha nkhumba kuti oxidize (kuwotcha) mpweya ndi zonyansa zina. Steelis ndiye amapangidwa mu ng'anjo ya okosijeni yokakamizidwa, komwe mpweya umasungunuka muchitsulo pa kutentha kwambiri. Kusiyanasiyana kwa kuuma ndi makhalidwe ena a chitsulo chingapezeke ndi kuwonjezera aloyi ndi annealing, kuzimitsa kuumitsa, ndi kutentha zitsulo. Ufa zitsulo (sintering) ndi ndondomeko imene ufa chitsulo kapena zitsulo zina pamodzi pa kuthamanga kwambiri popanda kutentha kwambiri. zoyenera kuumbidwa mafomu. Njirayi imagwiritsidwa ntchito popanga zida zachitsulo zofananira (zofanana monse). Chimodzi mwazinthu zothandiza kwambiri zachitsulo ndi maginito ake achilengedwe, omwe amataya kutentha. Magnetism imatha kuyambitsidwanso muzinthu zachitsulo poyambitsa magetsi. Maginito amitundu yonse ndi mawonekedwe amagwiritsidwa ntchito m'ma injini, zophwanya ma atomu, makina ojambulira a CT, ndi zowonera pa TV ndi makompyuta, kutchula ntchito zingapo. Maginito apamwamba amatha kupangidwa powonjezera zinthu zina (onani cobalt) ku iron yapamwamba kwambiri. Iron ndi chinthu chofunikira kwambiri chomwe chimapanga hemoglobini m'magazi, yomwe imanyamula okosijeni kupita ku ma cell a thupi lathu. Ndiwofunikanso kwambiri ngati chinthu chotsatira muzakudya, chomwe chimathandiza ndi theoxidation yazakudya kupanga mphamvu. Timafunikira ma milligrams 10 mpaka 18 tsiku lililonse, monga mchere wambiri.Iron imapezeka m'chiwindi ndi nyama, mazira, nkhono, masamba obiriwira, nandolo, nyemba, ndi tirigu. Kuperewera kwa iron kungayambitse kuchepa kwa magazi (kuchepa kwa maselo ofiira a magazi), kufooka, kutopa, kupweteka mutu, ndi kupuma movutikira. Kuchuluka kwachitsulo muzakudya kumatha kuwononga chiwindi, koma izi ndizovuta kwambiri. Chitsulo choyera ndi chinthu cha labotale ndipo sichimagwiritsidwa ntchito kwambiri m'mafakitale.
