I-calcium kunye ne-silicon: i-duo yekamva letekhnoloji? 

Uva okuninzi malunga ne-silicon, ngokucacileyo. Kodwa ukudibanisa ne-calcium? Kulapho incoko ifumana umdla, kwaye ngokungafihlisiyo, ukungaqondwa kancinci ngaphandle kwezangqa ezithile. Ayikokwenza intsimbi eyomeleleyo kwakhona.

Ngaphaya kweSithando somlilo: Ingcamango ephosakeleyo engundoqo

Uninzi lwabantu, nakwimimandla yetekhnoloji ekufutshane, babona i-silicon ye-calcium njengemveliso ye-metallurgical eninzi-isigxina esipheleleyo. Ingena kwi-ladle ye-deoxidation, mhlawumbi ye-nodularizing cast iron, kwaye lihlabathi layo. Ingcinga yokuba le ngxubevange ithobekileyo inokuba sisixhobo esibalulekileyo sokwenziwa kwemveliso, ugcino lwamandla, okanye i-electronics elandelayo ibonakala ngathi iyasolula. Leyo yimpazamo yokuqala: ukujongela phantsi indima yobunyulu bezinto eziphathekayo kunye nokusebenza okulungiselelwe. Xa usebenza nayo, uyaqonda ukuba ukusebenza akukhona nje kwimivimbo ebanzi 'yokongeza i-calcium,' kodwa kwimilinganiselo echanekileyo, ukulawulwa kokubandakanywa, kunye nobunjineli be-particle. Ibhetshi ene-morphology ethe kratya okanye i-trace elements inokuphazamisa inkqubo yokuphosa echanekileyo ngokupheleleyo. Ndiyibonile isenzeka.

Oku kukhokelela kwinqaku lesibini: ukukhangela. Ayizizo zonke i-silicon ye-calcium yenziwe ngokulinganayo. Ukuthembeka kwekhonkco lokubonelela, ukuhambelana ukusuka kwiqashiso ukuya kwiqashiso, kubaluleke kakhulu kunangaphambili. Iinkampani eziyiphatha njengempahla yorhwebo ziyatshiswa. Umzekelo, umvelisi wesilicon yelanga esisebenze naye wayenemiba eqhubekayo kunye nembewu yokungcola kwimibhobho yabo. Ingxaki yalandwa emva kokuguquguquka kwi i-calcium alloy isetyenziswe kwinyathelo lokuqala. Ukutshintshela kumboneleli onolawulo olungqongqo lwenkqubo, njenge I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd, esebenza enye yeendlela ezinkulu ezidibeneyo zokuvelisa, yenza umehluko obonakalayo. Ukuseta kwabo ngokusebenza okuzinikeleyo kwe-molybdenum, i-titanium, kunye nezinye izilungisi zicebisa ukugxila kwizinto ezithile, eyona nto iphambili.

I-nuance ikwiifom ezidibeneyo. Kunqabile ukuba ibe yiCaSi kwakhona. Yi-silicon barium calcium yokuphucula i-inoculation, okanye i-cored wire eneprofayili ethile yokuchithwa. Yilapho inxalenye ye-'tech' iqala ukukhwela. Awuthengi nje i-alloy; uthenga iphakheji yokusebenza. Ukukwazi kwenkampani ukunika olu luhlu-ukusuka kwi-ferrosilicon eqhelekileyo ukuya kwii-noduzers ezikhethekileyo kunye nocingo oludibeneyo-lubonisa ubunzulu obuzondla kwizicelo eziphezulu.

Ingxaki ye-Interface: Apho ithiyori idibana ne-Melt

Ngokwezinto eziphathekayo, isithembiso se i-silicon ye-calcium ihlala ikhubeka kujongano-ngokoqobo. Uyingenisa njani ngokufanelekileyo kwinkqubo yobushushu obuphezulu? Inaliti yocingo lweCored yayiyinguqu-mdlalo, kodwa yazisa iintloko zayo. Ukufumana isantya sokutya, ubungqingqwa besingxobo socingo, kunye nobunzulu bokuntywiliselwa bungalunganga kuthetha isivuno esibi, ukufutha, kunye nobumdaka obubiza imali eninzi. Ndikhumbula ulingo kwindawo yabasunguli apho sasilungiselela ukufakwa kwentsimbi entsha, ebhityileyo eludongeni. Ucingo olusemgangathweni lubangele ukusabela kobundlobongela. Kuye kwafuneka sisebenzisane nomvelisi we-alloy ukuze sidibanise ukubunjwa okungundoqo kunye nokuxinana ukuze sifumane ukukhululwa okugudileyo, okulawulwayo ngakumbi. Kwathatha izihlandlo ezithathu.

Emva koko kukho ingxaki yokulinganisa. Wongeza lo mathiriyeli ukuphembelela ulwakhiwo lwemicroscopic, kodwa ingxelo yexesha lokwenyani ikrwada. Uhlala uthembele kwi-post-cast spectroscopy kunye novavanyo lomatshini, okuthetha ukuba izilungiso ziyasilela. Lo ngumsantsa omkhulu. Ikamva alikho nje kwii-alloys ezingcono, kodwa kwinkqubo engcono yokudibanisa-iinzwa ezinokubona ukuphumelela kokuguqulwa ngexesha langempela, mhlawumbi ngohlalutyo lwe-thermal okanye i-ultrasonics ephezulu. Asikabikho.

Yiloo nto iinkqubo zoqinisekiso lomgangatho womlimi zingaxoxiswana. Ukuba uvavanyo lwabo lwangaphakathi alukho ngqongqo, ukuguquguquka kwakho okusezantsi kuyenyuka. Iseti epheleleyo yezixhobo zokuvavanya ngokuchanekileyo, njengoko kukhankanyiwe kwiprofayili yeXinxin Silicon Industry, ayithengisi i-fluff; sisiseko sokuba nabani na ofuna ukuhamba ngaphaya kwemveliso yempahla. Yiyo into evumela ukuphuhliswa kwezo mveliso zilungiselelwe njenge-deoxidizers edibeneyo edibeneyo okanye i-desulfurizers.

I-Aside eKhawulezayo kwiSilicon Metal ngokwayo

Awukwazi ukuthetha ngale duo ngaphandle kokuvuma icala le-silicon. Ukutyhala ubunyulu obuphezulu intsimbi ye-silicon yepolysilicon kunye ne-elektroniki yenza iluphu yengxelo enomdla.

Ke imfuno yokuqhuba itekhnoloji yesilicon esulungekileyo ikwaphucula ubuchule bokusebenzisa ialloys calcium. Yinguquko yezoshishino ye-symbiotic.

Amagqabantshintshi oMthetho olandelayo: Amandla kunye noLongezo

Ingaba le nto igqitha phi isinyithi esiqhelekileyo? Iindawo ezimbini zibonisa ukukhanya. Okokuqala, i-anode yebhetri. I-silicon yigrail engcwele ye-lithium-ion umthamo, kodwa ukwandiswa kwayo ngumbulali. Uphando kwii-anode ezidibeneyo zisebenzisa i-calcium-silicon intermediates okanye i-coatings ukulawula uxinzelelo kunye nokwenza ngcono i-SEI layers iyaqhubeka. Kungethuba, kodwa i-chemistry esisiseko iyathembisa. Ulwazi-ndlela oluvela kwimveliso elawulwayo, i-fine-particle iingxube ze-silicon inokudluliselwa ngokuthe ngqo.

Okwesibini, imveliso eyongezelelweyo. Ukuprintwa ngesinyithi, ngakumbi ezo zisebenza njenge-aluminiyam okanye i-titanium alloys, kudla ngokufuna ukukhutshwa okuchanekileyo kwe-deoxidation kunye nokulungiswa kweenkozo kwindawo. I-powder feedstock eyenziwe ngomzuzu, i-dispersions efanayo ye-calcium-silicon-based modifiers ingaba yindlela eya kwiipropati ezingcono eziprintiweyo. Kumalunga nokuhambisa inyathelo lokuguqulwa kwezinto eziphathekayo ukusuka kwi-bulk melt ukuya kwi-particle powder. Oku kufuna uhlobo oluhluke ngokupheleleyo lwenyama yealloyi, umngeni kubavelisi bemveli.

Ayizizo zinto ziqinisekileyo. Babheje. Kwaye bafuna abavelisi bacinge njengababoneleli besisombululo sezinto eziphathekayo, hayi nje izinyibilikisi. Kuthetha ukutyala imali kwi-R&D kwizicelo ezinokuthi zingabinayo intengiso ishumi leminyaka. Ngaba ishishini linawo umonde? Abanye benza njalo. Abadlali abakhulu, abadityanisiweyo abaneenkqubo zomgangatho osekiweyo babekwe kakuhle kwipivot kuba sele beluqonda ulawulo olukwinqanaba elisisiseko.

Ukujongwa kweNyaniso: Iindleko, isikali, kunye noxinzelelo oluluhlaza

Masingathwali kude. Kuwo onke amandla, umqhubi obalaseleyo we i-silicon ye-calcium imveliso iya kuba yintsimbi kunye namashishini e-Foundry kwikamva elibonakalayo.
