Maxaa Aluminium Oxide loo isticmaalaa?
Alumina (Al2O3)Waxay u adeegtaa sida alaabta ceeriin ee balaadhan oo ah alaabta dhoobada horumarsan iyo sida wakiilka firfircoon ee farsamaynta kiimikada, oo ay ku jiraan adsorbents, kiciyayaasha, microelectronics, kiimikooyinka, warshadaha hawada, iyo meelaha kale ee farsamada sare. Astaamaha sare ee alumina ayaa bixin kara waxay ka dhigi kartaa mid ku habboon in loo isticmaalo codsiyo badan. Qaar ka mid ah codsiyada ugu caansan ee ka baxsan wax soo saarka aluminium ayaa hoos ku taxan. Buuxiyeyaasha Ahaanshaha si cadaalad ah kiimiko ahaan aan firfircoonayn oo cad, aluminium oxide ayaa ah buuxinta la door biday balaastigga. Qurxinta Catalysis Aluminium oxide wuxuu kiciyaa falcelinno kala duwan oo faa'iido u leh warshadaha. Nadiifinta gaasta. Aluminium oxide ayaa si weyn loo isticmaalaa si looga saaro biyaha qulqulka gaaska. Naaxsan Aluminium oxide waxaa loo isticmaalaa adkaanteeda iyo xooggeeda. Rinjiyeynta Qalabyada aluminium oxide waxaa loo isticmaalaa rinjiga si loo muujiyo saamaynta qurxinta. Fiber isku dhafan. Aluminium oxide ayaa loo adeegsaday dhowr qalab fiber tijaabo ah iyo ganacsi oo loogu talagalay codsiyada waxqabadka sare leh (tusaale, Fiber FP, Nextel 610, Nextel 720). Hubinta jirka.Qaar ka mid ah hubka jirka ayaa isticmaala taarikada dhoobada alumina, badanaa marka lagu daro aramid ama UHMWPE taageerada si loo gaaro waxtarka ka hortagga badi hanjabaadaha qoryaha. Ilaalinta nabarrada. Aluminium oxide waxaa lagu kori karaa dahaarka aluminiumka iyadoo la isticmaalayo anodizing ama balaasmaha oxidation electrolytic. dahaarka korontada. Aluminium oxide waa daahaye koronto oo loo isticmaalo sida substrate (silicon on sapphire) ee wareegyada isku dhafan laakiin sidoo kale sida tunnel tunnel ee samaynta qalabyada sare sida transistor-ka elektarooniga ah iyo aaladaha faragelinta quantum superconducting (SQUIDs).
Aluminium Oxid, Ahaanshaha dielectric leh faraqa band oo aad u weyn, ayaa loo isticmaalaa sida xannibaadaha daboolka ee capacitors. Iftiinka, aluminium oxide translucent waxaa loo isticmaalaa nalalka uumiga sodium qaarkood. Aluminium oxide ayaa sidoo kale loo isticmaalaa diyaarinta dahaarka ganaaxyada ee nalalka dhaadheer. Shaybaarada kimisteriga, aluminium oxide ayaa dhexdhexaad u ah chromatography, oo laga heli karo aasaasiga (pH 9.5), acidic (pH 4.5 marka biyaha lagu jiro) iyo qaabab dhexdhexaad ah. Codsiyada caafimaadka iyo caafimaadka waxaa ka mid ah sida walxaha beddelka miskaha iyo kaniiniyada ilaalinta uurka. Waxa loo isticmaalaa scintillator ahaan iyo qiyaasaha ilaalinta shucaaca iyo codsiyada daawaynta ee sifooyinkeeda iftiinka iftiinka leh. Dahaarka foornooyinka heerkulka sare waxaa badanaa laga soo saaraa aluminium oxide. Qaybo yaryar oo aluminium oksaydh ah ayaa inta badan loo isticmaalaa sida jajabyada karkaraya ee kimistariga. Waxa kale oo loo isticmaalaa in lagu sameeyo dab-bakhtiyeyaal. Isticmaalka habka buufinta balaasmaha oo lagu qaso titania, waxaa lagu dahaadhay dusha bareegga ee qaar ka mid ah geesaha baaskiilka si ay u bixiso naaxinta iyo xirashada iska caabbinta. Inta badan indhaha dhoobada ee ulaha kalluumeysiga waa giraangiro wareeg ah oo laga sameeyay aluminium oksaydh. Qaabka budada ah ee ugu fiican, ee loo yaqaan Diamantine, aluminium oxide waxa loo isticmaalaa sida wax-soo-saarka saafiga ah ee saacadaha samaynta iyo samaynta saacada. Aluminium oxide sidoo kale waxaa loo isticmaalaa daaha of stanchions ee iskutallaabta mootada iyo warshadaha baaskiilka buuraha. Daahan waxaa lagu daraa molybdenum disulfate si ay u bixiso sifeynta muddada dheer ee dusha sare.
