I-High Purity Nano Fe Powder ye-High-Entropy Alloys

Ukusetshenziswa kwezimboni zensimbi njengezinsimbi zekhabhoni kuningi futhi kudlula noma yimaphi ama-410 IRONOkunye ama-alloys. Izinsimbi zekhabhoni ziyingxube yensimbi equkethe ikhabhoni ngezilinganiso ezihlukene, ngokuvamile ifinyelela ku-1.7% wekhabhoni. Ezinye izinsimbi nazo zifakwe ku-carbon steels ukukhiqiza izinsimbi ezine-alloy ephansi. Izinsimbi ezinjalo ngokuvamile ziyi-nickel ne-chromium futhi zihlukaniswa njengensimbi engagqwali, izinsimbi zamathuluzi, nezinsimbi ezikwazi ukumelana nokushisa. Ama-alloys ensimbi engeyona eyensimbi njenge-cast iron, insimbi ekhandiwe, i-nickel iron ne-silicon iron nawo anemisebenzi eminingi ebalulekile. Okunye ukusetshenziswa okubalulekile kwensimbi kunjenge-catalyst yezimboni. Isetshenziswa ekuqanjweni kwe-catalyst kunqubo ye-Haber yokuhlanganiswa kwe-ammonia, kanye nenqubo ye-Fischer-Tropsch yokukhiqiza uphethiloli wokwenziwa.Lokhu okulandelayo ezinye izibonelo zezicelo ezivamile: imithi, izibulala-zinambuzane, i-powder metallurgy nokunye; njengejeneretha ye-hydrogen eshisayo, i-gel propellant, i-activator evuthayo, i-catalyst, i-adsorbent yokuhlanza amanzi, i-ejenti esebenzayo ye-sintered, njll;isetshenziselwa imikhiqizo ye-powder metallurgy, zonke izinhlobo zezingxenye zemishini nemikhiqizo yezingxenye, imikhiqizo ye-carbide enosimende, njll; njenge-ejenti yokunciphisa kanye nokusetshenziselwa ukukhiqiza usawoti wensimbi kanye nemboni yezogesi; njengezithako zokudla okunomsoco (i-iron fortifier), zokuphonsa, noma njenge-ejenti yokunciphisa; embonini ye-electronics, i-powder metallurgy. I-ayoni iyiminerali esetshenziswa ekuqiniseni ukudla edingekayo ukuze kuvinjwe i-anemia, enciphisa ukugcwala kwe-hemoglobin ngaleyo ndlela nenani lomoya-mpilo elilethwa ezicutshini. Imithombo ihlanganisa i-ferric ammonium sulfate, i-chloride, i-fructose, i-glycerophosphate, i-nitrate, i-phosphate, i-pyrophosphate ne-ferrous ammonium sulfate, i-citrate, i-sulfate, ne-sodium iron edta. ifomu le-ferric (fe3+) iyinsimbi esesimweni esiphezulu se-valence futhi ifomu le-ferrous (fe2+) iyinsimbi esesimweni esiphansi se-valence. umthombo wensimbi akufanele ushintshe umbala noma wengeze ukunambitheka futhi kufanele uzinze. izimpushana zensimbi zikhiqiza ukushintsha kombala okuphansi kanye ne-rancidity. isetshenziselwa ukuqinisa ufulawa, izinto ezibhakwayo, i-pasta, nemikhiqizo yezinhlamvu. Ukuncibilika kwensimbi ensimbini yayo kwenzeka esithandweni somlilo lapho i-carbon (coke) kanye ne-limestone kushiswa ngensimbi okuholela ekuncipheni kwensimbi ensimbi futhi kuguqulwe insimbi encibilikisiwe, ebizwa ngokuthi "insimbi yengulube." Insimbi yengulube encibilikisiwe isaqukethe ikhabhoni ne-silicon kanye nokunye ukungcola njengoba iqoqana ngaphansi kwesithando ne-slag encibilikisiwe entanta phezu kwensimbi. Zombili zicutshungulwa futhi zikhishwe. Le nqubo ingaba yinto eqhubekayo njengoba ezinye izithako zingengezwa njengoba insimbi ne-slag kukhishwa ngaphansi kwesithando somlilo.Leli fomu lensimbi aliwusizo kakhulu emikhiqizweni yokukhiqiza, njengoba liqinile futhi alinamandla kakhulu.Enye yentuthuko enkulu. kubuchwepheshe bokuncibilikisa insimbi kwaba ukuthuthukiswa kwenqubo yeBessemer nguHenry Bessemer (1813-1898). Kule nqubo, umoya ocindezelweyo noma i-oxygen iphoqelelwa ngensimbi yengulube encibilikisiwe ukuze i-oxidize (ishise) ikhabhoni nokunye ukungcola. I-Steelis yabe isikhiqizwa esithandweni somoya-mpilo esiphoqelelwe, lapho ikhabhoni ichithwa khona ensimbi emazingeni okushisa aphezulu kakhulu. Ukwehluka kokuqina kanye nezinye izici zensimbi kungafinyelelwa ngokwengezwa kwama-alloys nangokuyidonsa, ukucisha ukuqina, kanye nokufudumeza insimbi. I-Powder metallurgy (sintering) inqubo lapho insimbi eyimpuphu noma ezinye izinsimbi zihlanganiswa ndawonye ngokucindezela okukhulu ngaphandle kokushisa okuphezulu vumela amafomu abunjiwe. Le nqubo isetshenziselwa ukukhiqiza izingxenye zensimbi ezifanayo (iyunifomu kuyo yonke) izingxenye zensimbi.Enye yezici eziwusizo kakhulu zensimbi yizibuthe zayo zemvelo, ezilahlekelwa amazinga okushisa aphezulu. I-Magnetism ingase yethulwe emikhiqizweni yensimbi ngokufakwa ngogesi. Ozibuthe babo bonke osayizi nobumo basetshenziswa kumamotho, ama-athomu smasher, izithwebuli ze-CT, kanye nezikrini ze-TV nezekhompyutha, ukubiza ukusetshenziswa okumbalwa. Ozibuthe abakhulu bangakhiwa ngokwengeza ezinye izakhi (bheka i-cobalt) ensimbi yekhwalithi ephezulu.I-ayoni iyisici esibalulekile esakha i-hemoglobin egazini, ehambisa umoya-mpilo kumaseli emizimbeni yethu. Kubaluleke kakhulu futhi njenge-trace element ekudleni, okusiza nge-oxidation yokudla ukukhiqiza amandla. Sidinga cishe amamiligremu ayi-10 kuya kwangu-18 e-irone ngosuku, njenge-trace mineral.I-ayoni itholakala esibindini nasemikhiqizweni yenyama, amaqanda, izimbaza, imifino enamahlamvu aluhlaza, uphizi, ubhontshisi, kanye nokusanhlamvu okuphelele. Ukuntuleka kwe-iron kungase kubangele i-anemia (isibalo esiphansi samangqamuzana abomvu egazi), ubuthakathaka, ukukhathala, ubuhlungu bekhanda, nokuphelelwa umoya. I-iron eyengeziwe ekudleni ingabangela ukulimala kwesibindi, kodwa lesi yisimo esingajwayelekile. Insimbi ehlanzekile iyimpahla yaselabhorethri kakhulu futhi ayitholi ukusetshenziswa okukhulu kwezimboni.
