Maxaa loo isticmaalaa Aluminium Oxide?
Alumina (Al2O3)Waxay u adeegtaa sidii walxo ceeriin ah oo loogu talagalay noocyo badan oo badeecooyin dhoobo ah oo horumarsan iyo wakiil firfircoon oo ku saabsan farsamaynta kiimikada, oo ay ku jiraan nuugayaasha, kiciyeyaasha, microelectronics, kiimikooyinka, warshadaha hawada sare, iyo meelo kale oo tiknoolajiyad sare leh. Astaamaha sare ee alumina ay bixin karto ayaa ka dhigaya mid ku habboon in loo isticmaalo codsiyo badan. Qaar ka mid ah codsiyada ugu badan ee ka baxsan wax soo saarka aluminiumka ayaa hoos ku taxan. Buuxiyeyaasha. Maadaama ay tahay mid kiimiko ahaan aan firfircoonayn oo cad, aluminium oxide waa buuxinta ugu wanaagsan ee balaastikada. Muraayadaha. Qaabab badan oo galaas ah ayaa leh aluminium oxide oo ah maaddooyin. Catalysis Aluminium oxide waxay kicisaa falcelinno kala duwan oo waxtar u leh warshadaha. Nadiifinta gaaska. Aluminium oxide si weyn ayaa loo isticmaalaa in biyaha laga saaro durdurrada gaaska. Waa mid xoqan. Aluminium oxide waxaa loo isticmaalaa adkaanteeda iyo xooggeeda. Rinjiga. Duubabka aluminium oxide waxaa loo isticmaalaa rinjiga si loo helo saameyn qurxin oo milicsan. Faybar isku dhafan. Aluminium oxide waxaa loo isticmaalay dhowr walxood oo fiilo tijaabo ah iyo ganacsi ah oo loogu talagalay codsiyada waxqabadka sare leh (tusaale, Fiber FP, Nextel 610, Nextel 720). Hubka jirka. Qaar ka mid ah hubka jirka waxay isticmaalaan saxannada dhoobada ah ee alumina, badanaa iyadoo lala kaashanayo taageerada aramid ama UHMWPE si loo gaaro wax ku oolnimo ka dhan ah khataraha qoryaha badankood. Ilaalinta xoqidda. Oksijiinta aluminiumka waxaa lagu kori karaa dahaar ahaan aluminiumka iyadoo la isticmaalayo anodising ama oksaydheynta elektrolytic-ga plasma. Dahaarka korontada. Oksijiinta aluminiumka waa dahaar koronto oo loo isticmaalo substrate ahaan (silicon on sapphire) wareegyada isku dhafan laakiin sidoo kale waa caqabad god oo loogu talagalay sameynta aaladaha superconducting sida transistors-ka elektaroonigga ah ee keli ah iyo aaladaha faragelinta quantum-ka ee superconducting (SQUIDs).
Aluminium Oxide, oo ah dielectric leh dalool xarig weyn, ayaa loo isticmaalaa sidii caqabad dahaadh ah oo ku jirta kapastors-ka. Nalalka, oxide aluminium ah oo hufan ayaa loo isticmaalaa laambadaha uumiga sodium qaarkood. oxide aluminium waxaa sidoo kale loo isticmaalaa diyaarinta dahaarka dahaarka ee laambadaha fluorescent-ka ee is haysta. Shaybaarrada kiimikada, oxide aluminium waa dhexdhexaad loogu talagalay koromagrafiga, oo laga heli karo aasaaska (pH 9.5), aashitada (pH 4.5 marka biyaha lagu jiro) iyo qaacidooyinka dhexdhexaadka ah. Codsiyada caafimaadka iyo caafimaadka waxaa ka mid ah walxo lagu beddelo sinta iyo kiniiniyada xakamaynta dhalmada. Waxaa loo isticmaalaa sidii scintillator iyo dosimeter loogu talagalay ilaalinta shucaaca iyo codsiyada daaweynta ee sifooyinka iftiinka ee indhaha lagu kiciyay. Dahaarka foornooyinka heerkulka sare leh waxaa badanaa laga sameeyaa aluminium oksaydh. Qaybo yaryar oo oxide aluminium ah ayaa badanaa loo isticmaalaa sidii jajab karkaraya kiimikada. Waxaa sidoo kale loo isticmaalaa in lagu sameeyo dahaadhayaasha dabka. Iyadoo la adeegsanayo habka buufinta balaasmaha oo lagu qaso titania, waxaa lagu dahaadhay dusha sare ee biriiga ee qaar ka mid ah cidhifyada baaskiilka si loo bixiyo xoqid iyo iska caabin xirasho. Inta badan indhaha dhoobada ah ee ku yaal ulaha kalluumeysiga waa faraanti wareegsan oo laga sameeyay aluminium oksaydh. Qaabkeeda ugu fiican ee budada ah (caddaan), oo loo yaqaan Diamantine, aluminium oksaydh waxaa loo isticmaalaa xoqid heer sare ah oo lagu nadiifiyo saacadaha iyo sameynta saacadaha. Aluminium oksaydh waxaa sidoo kale loo isticmaalaa dahaarka stanchions ee warshadaha mootada iskutallaabta iyo baaskiillada buuraha. Dahaarkan waxaa lagu daraa molybdenum disulfate si loo siiyo saliidayn muddo dheer ah dusha sare.
