I-Aluminium Oxide isetshenziselwani?
I-Alumina (Al2O3)isebenza njengezinto zokusetshenziswa zohlu olubanzi lwemikhiqizo ye-ceramic ethuthukisiwe kanye ne-ejenti esebenzayo ekucutshungulweni kwamakhemikhali, kufaka phakathi ama-adsorbents, ama-catalyst, ama-microelectronics, amakhemikhali, imboni yezindiza, kanye neminye indawo yobuchwepheshe obuphezulu. Izici ezinhle kakhulu i-alumina engazinikeza zenza kube kuhle ukusetshenziswa ezinhlelweni eziningi. Ezinye zezinhlelo zokusebenza ezivame kakhulu ngaphandle kokukhiqizwa kwe-aluminium zibhalwe ngezansi. Ama-Fillers. Njengoba i-aluminium oxide ingangeni kahle futhi imhlophe, i-aluminium oxide iyinto ethandwayo yokugcwalisa amapulasitiki. Ingilazi. Izinhlobo eziningi zengilazi zine-aluminium oxide njengesithako. I-Catalysis I-aluminium oxide ivuselela ukusabela okuhlukahlukene okuwusizo ezimbonini. Ukuhlanzwa kwegesi. I-aluminium oxide isetshenziswa kabanzi ukususa amanzi emifudlaneni yegesi. I-Abrasive. I-aluminium oxide isetshenziselwa ubulukhuni bayo namandla ayo. Upende. Ama-flakes e-aluminium oxide asetshenziswa kupende ukuze kuboniswe imiphumela yokuhlobisa. I-fiber ehlanganisiwe. I-aluminium oxide isetshenziswe ezintweni ezimbalwa zefayibha zokuhlola nezentengiselwano zezinhlelo zokusebenza eziphezulu (isb., I-Fiber FP, i-Nextel 610, i-Nextel 720). Izivikelo zomzimba. Ezinye izivikelo zomzimba zisebenzisa amapuleti e-alumina ceramic, ngokuvamile ahlanganiswe ne-aramid noma i-UHMWPE backing ukuze kufezwe ukusebenza kahle ngokumelene nezinsongo eziningi zezibhamu. Ukuvikelwa kokuguguleka. I-aluminium oxide ingakhuliswa njengesembozo ku-aluminium ngokufaka i-anodizing noma nge-plasma electrolytic oxidation. Ukufakwa kukagesi. I-aluminium oxide iyisivikelo sikagesi esisetshenziswa njenge-substrate (i-silicon ku-sapphire) yamasekethe ahlanganisiwe kodwa futhi njengesivikelo somhubhe wokwenziwa kwamadivayisi e-superconducting afana nama-transistors e-electron eyodwa kanye namadivayisi e-superconducting quantum interference (ama-SQUID).
I-aluminium Oxide, njengoba iyi-dielectric ene-band gap enkulu kakhulu, isetshenziswa njengesivikelo sokuvimbela ukushisa kuma-capacitor. Ekukhanyeni, i-aluminium oxide ekhanyayo isetshenziswa kwezinye izibani zomusi we-sodium. I-aluminium oxide isetshenziswa futhi ekulungiseleleni ukumiswa kokumboza ezibanini ezikhanyayo ezikhanyayo. Emalabhorethri amakhemikhali, i-aluminium oxide iyindlela yokwelapha i-chromatography, etholakala ngesisekelo (pH 9.5), i-acidic (pH 4.5 uma isemanzini) kanye nezindlela ezingathathi hlangothi. Izicelo zezempilo nezokwelapha zifaka phakathi njengento esetshenziswa ekufakweni kwe-hip esikhundleni namaphilisi okulawula ukuzalwa. Isetshenziswa njenge-scintillator kanye ne-dosimeter yokuvikela imisebe kanye nezicelo zokwelapha ngenxa yezakhiwo zayo zokukhanya ezivuselelwa yi-optically. Ukufakwa kokushisa kwama-oven okushisa okuphezulu kuvame ukukhiqizwa nge-aluminium oxide. Izingcezu ezincane ze-aluminium oxide zivame ukusetshenziswa njengama-chips abilayo kumakhemikhali. Iphinde isetshenziselwe ukwenza ama-spark plug insulators. Isebenzisa inqubo yokufafaza nge-plasma futhi ixutshwe ne-titania, imbozwa ebusweni bokubhuleka kwamanye ama-rim ebhayisikili ukuze inikeze ukumelana nokuguguleka. Amehlo amaningi e-ceramic ezindongeni zokudoba ayizindandatho eziyindilinga ezenziwe nge-aluminium oxide. Ngendlela yayo empuphu (emhlophe) enhle kakhulu, ebizwa ngokuthi i-Diamantine, i-aluminium oxide isetshenziswa njengesithambisi esicwebezelayo esingcono kakhulu ekwenzeni amawashi nasekwenzeni amawashi. I-aluminium oxide isetshenziswa futhi ekumbozeni ama-stanchions embonini yezimoto kanye neyamabhayisikili asezintabeni. Lokhu kuhlanganiswa kuhlanganiswe ne-molybdenum disulfate ukuze kuhlinzekwe ukuthambisa okuhlala isikhathi eside ebusweni.
