Alumina-da kiimikada ah way kala duwan tahay, sida ku cad heerka warshadaha birta aan birta lahayn ee YS/ tan 619-2007 "nooca kiimikada alumina iyo magaca sumadda", sida ku cad halabuurka kiimikada ee alumina kiimikada ah waxaa loo qaybiyaa 5 qaybood: taxanaha aluminium hydroxide, taxanaha gaarka ah ee aluminium oxide, taxanaha quasi thin alumina, taxanaha zeolite iyo taxanaha sibidhka calcium aluminate.
Hadda, polyaluminium chloride, sodium silicate, fluoride milix iyo cusbo kale oo aluminium ah, sodium aluminate, gallium iyo gallium iskudhisyo, qayb ka mid ah dhoobada alumina iyo corundum refractories ayaa sidoo kale lagu daray qaybta kiimikada alumina.
Sannadkii 1910, Alcoa waxay soo saartay oo iibisay dufcaddii ugu horreysay ee alumina calcined adduunka, taas oo ahayd agabka ceeriin ee lagu soo saaro abrasives cad oo corundum ah.
Alumina kiimikada waxaa lagu gartaa noocyo kala duwan oo alaab ah, qiimo sare oo lagu daray, macluumaad farsamo oo sare, goobo codsi oo ballaaran oo ballaaran, qiimo deggan, deegaan u fiican, sidaas darteed, waxay noqotay laan aad muhiim u ah warshadaha aluminiumka.
Dalal badan oo adduunka ah ayaa si weyn u maalgeliyey horumarinta warshadaha kiimikada alumina. Alcoa waxay ahaan jirtay soo saaraha kiimikada alumina ee ugu weyn adduunka, iyadoo leh 24 shirkadood oo wax soo saar ah, oo daboolaya dhammaan waddamada iyo gobollada waaweyn ee adduunka, iyagoo soo saaraya in ka badan 220 nooc iyo in ka badan 1000k tan / a. Kadib sannadkii 2007, saxanka kiimikada alumina ayaa loo wareejiyay shirkadda anmai ee Netherlands.
Japan waa wax soo saarka kiimikada alumina ee ugu awoodda badan adduunka, isticmaalka, wax soo saarka qiyaastii 1000 k, 2012 tan, waxayna sii waday inay si tartiib tartiib ah u korto, kala duwanaanshuhu waa kan ugu badan adduunka, Japan ma soo saarto alumina heerka birta, laakiin waxay ogaatay baaxadda wax soo saarka kiimikada ee alumina, seriation, sayniska sare iyo tignoolajiyada, ilaalinta deegaanka iyo qiimaynta kharashka, wax soo saarka marka laga reebo baahida gudaha, dhoofinta ayaa gaartay 25%. In ka badan 85% wax soo saarka kiimikada alumina ee Japan waxaa soo saara warshadaha kiimikada ee sumitomo, showa denko iyo biraha fudud ee Japan.
Qiyaastii 1940, Mareykanka, Japan iyo Yurub oo ku saabsan cilmi-baarista kiimikada alumina ee heer sare ah, ilaa 1970-yadii, qaar ka mid ah wadamada horumaray warshadaha ee wadamada shisheeye waxay ahaayeen horumar weyn.
Sida laga soo xigtay tirakoobka ururka caalamiga ah ee warshadaha aluminiumka, sannadkii 1975, wadarta wax soo saarka alumina ee dalalka reer galbeedka waa qiyaastii 20344k tan, wax soo saarka kiimikada alumina wuxuu ahaa 1699k tan, taasoo ka dhigan 8.3% wadarta wax soo saarka; Sannadkii 2000, wadarta wax soo saarka alumina ee adduunka oo dhan waxay ahayd qiyaastii 51200k tan, halka wax soo saarka kiimikada alumina uu ahaa 4800k tan, taasoo ka dhigan 9.4% wadarta wax soo saarka. Sannadkii 2008, wax soo saarka caalamiga ah ee alumina heerka birta ah wuxuu ahaa 60496k tan halka alumina kiimikada ah uu ahaa 4638k tan, taasoo ka dhigan 7.12% wadarta wax soo saarka. Sannadkii 2012, wadarta wax soo saarka alumina adduunka wuxuu ahaa 95,705k tan, wax soo saarka alumina kiimikada ahna wuxuu ahaa 85,80k tan, taasoo ka dhigan 9% wadarta wax soo saarka. Laga soo bilaabo 2008 ilaa 2012, celceliska sanadlaha ah Heerka kobaca alumina kiimikada adduunka wuxuu ahaa 16.6%, qiyaastii 11 boqolkiiba dhibcood ayaa ka sarreeya celceliska heerka kobaca sanadlaha ah ee aluminiumka aasaasiga ah.
Warshadaha kiimikada ee alumina-da Shiinaha ayaa si dhakhso ah u bilaabmay. Qiyaastii 1961, si loo xalliyo yaraanta agabka ceeriin ee warshadaha elektaroonigga ah, warshadda aluminiumka ee Shandong (oo hadda loo yaqaan shirkadda warshadaha aluminiumka ee Shandong, LTD.) ayaa markii ugu horreysay samaysay alumina sodium yar waxayna bilowday cilmi-baarista, horumarinta iyo soo saarista alumina-da kiimikada ee Shiinaha.
Sannadihii 1970-meeyadii, si loo qanciyo batroolka, kiimikada, kuwa aan la isticmaalin, dhoobada, daawooyinka, ilaalinta deegaanka, hubka, hawada sare iyo warshadaha kale, baahida loo qabo kiimikooyinka alumina, warshadda aluminiumka shandong, machadka cilmi-baarista birta fudud ee zhengzhou waxayna leedahay horumarinta iyo soo saarista alumina firfircoon, wakiilka ka saarista fluoride ee alumina arsenic, hydroxide aluminium bir yar, alumina saafi ah oo sare, dhoobada alpha Al2O3, lagu buufiyo alumina iyo 24 nooc oo kale oo alaab cusub ah.
Sannadihii 1980-meeyadii, wax soo saarka kiimikada alumina ee Shiinaha wuxuu galay xilli horumar degdeg ah, alaabooyin cusubna way soo baxeen. Iyadoo ay matalaan machadka cilmi-baarista birta fudud ee zhengzhou, shirkadda warshadaha aluminiumka ee shandong, ltd. iyo shirkadda warshadaha aluminiumka ee Shiinaha ee Great Wall, ltd, waxaa la dhisay ilaa 60 khadad wax soo saar alumina oo gaar ah. Shirkado badan oo alumina ah oo ku yaal deegaannada ku xeeran ayaa dhisay dufcad wax soo saar alumina kiimiko ah oo shirkado gaar loo leeyahay ah, waxay isticmaalaan walxo cayriin ah oo gudaha ama dibadda laga keeno si ay u soo saaraan noocyo kala duwan oo alumina kiimiko ah.
Shiinuhu waa waddan weyn oo wax soo saar alumina ah, oo adeegsanaya tiknoolajiyad wax soo saar oo ka badan waddan kale, way fududahay in la xaqiijiyo laanta wax soo saarka kiimikada alumina iyadoo lagu tallaalayo habka tignoolajiyada, gaar ahaan aluminium hydroxide oo laga soo saaro habka sintering, kaas oo leh cadaan dabiici ah oo sarreeya.
Ka dib in ka badan 50 sano oo horumar ah, warshadaha kiimikada ee alumina-da Shiinaha waxay saameyn weyn ku leeyihiin suuqyada gudaha iyo dibadda, buuxinta aluminium hydroxide-ka iyo alaabada kale ayaa sidoo kale si fiican looga yaqaanaa suuqa caalamiga ah.
Si kastaba ha ahaatee, marka la barbardhigo Mareykanka, Jarmalka, Japan, kiimikada alumina-da Shiinaha iyadoon loo eegin tayada badeecada, noocyada, baaxadda wax soo saarku waxay leeyihiin farqi weyn, sababta aasaasiga ah waa dib u dhac ku yimid tiknoolajiyada wax soo saarka iyo qalabka, wax soo saarka iyo adeegsiga cilmi-baarista aragtida aasaasiga ah kuma filna, awoodda hal-abuurka oo daciif ah, horumarinta suuquna kuma filna.
