Yini i-aluminium oxide esetshenziselwe?
I-Alumina (Al2o3)Isebenza njengento eluhlaza yohlobo olubanzi lwemikhiqizo ebanzi ye-ceramic futhi njenge-ejenti esebenzayo ekusebenzeni kwamakhemikhali, kufaka phakathi ama-adsorbents, ama-catalysts, ama-microelectonics, amakhemikhali, imboni ye-aerospace, nenye indawo ephezulu. Izici eziphakeme ze-Alumina zinganikezela zenze ilungele ukusetshenziswa kuzicelo eziningi. Ezinye izinhlelo ezivame kakhulu ngaphandle komkhiqizo we-aluminium zibhalwe ngezansi. Ama-fillers. Ukuba ngu-inert ngokweqile ngamakhemikhali kanye nomhlophe, i-aluminium oxide iyisihlungi esithandwayo samapulasitiki. Iglasimu.Amakhi wengilazi ye-Glass ine-aluminium oxide njengesithako. I-Catalysis aluminium oxide catalyses ahlukahlukene okusabela okuwusizo kakhulu. Ukuhlanzwa kwegesi. I-Aluminium Oxide isetshenziswa kabanzi ukususa amanzi emifudlaneni yegesi. Abrasive. I-Aluminium Oxide isetshenziselwa ubulukhuni bayo namandla. Upende. I-Aluminium oxide flakes isetshenziswa ngopende ngemiphumela yokuhlobisa. I-Composite fiber. I-Aluminium Oxide isetshenzisiwe ezintweni ezimbalwa zokuhlola kanye nezentengiso ze-fiber izicelo zokusebenza okuphezulu (isib. I-FP FP, Nextel 610, Nextel 720). Izikhali zomzimba.some izikhali zomzimba zisebenzisa amapuleti we-alumina ceramic, imvamisa ngokuhlanganiswa ne-ARAMID noma i-UHMWPE exhaswa ukufezekisa ukusebenza kwezingsongo eziningi ze-rifle. Ukuvikela i-abrasion. I-Aluminium Oxide ingatshalwa njengokuhlanganiswa kwe-aluminium ngokufaka i-anodizing noma nge-plasma electrolytic oxidation. Ukufakwa kukagesi. I-Aluminium Oxide i-insulator kagesi esetshenziswa njenge-substrate (i-silicon on sapphire) ukuthola izifunda ezihlanganisiwe kodwa futhi njengesithiyo somhubhe ngokuqanjwa kwamadivayisi we-superconductip
I-Aluminium Oxide, Ukuba yi-dielectric ene-band gag enkulu, kusetshenziswa njengesithiyo esifaka ama-capacitors. Ekukhanyeni, i-aluminium oxide isetshenziswa kwamanye amalambu we-sodium vapor. I-Aluminium Oxide nayo isetshenziswa ekulungiseleleni ukumiswa kokuhlanganiswa ngamalambu e-compact fluorescent. Ku-Cheminry Laboatories, i-Aluminium Oxide iyindlela ephakathi kwe-chromatography, etholakala ku-Basic (PH 9.5), i-acidic (PH 4.5 lapho amanzi) kanye nokwakheka okungathathi hlangothi) kanye nokwakheka okungathathi hlangothi. Izicelo zezempilo kanye nezokwelapha zikufaka njengento ebonakalayo ekushintshelweni kwe-hip kanye namaphilisi okulawula ukuzalwa. Isetshenziswa njenge-scintillator ne-dosimeter yokuvikelwa kwemisebe kanye nokwelashwa kwezicelo zokwelapha ngezinto zayo ezivuselelwa kalula. Ukufakelwa kwezimwunda okushisa okuphezulu kuvame ukwenziwa kusuka ku-aluminium oxide. Izingcezu ezincane ze-aluminium oxide zivame ukusetshenziswa njengama-chips abilayo ku-Chemistry. Kusetshenziselwa futhi ukwenza ama-plug plug plug. Usebenzisa inqubo yokufafaza ye-plasma futhi exutshwe neTitania, ihlanganiswe endaweni yokubhula kwezinye izinhlaka zamabhayisekili ukuhlinzeka ukumelana nokugqoka. Iningi le-ceramic amehlo ezinduku zokudoba likhona izindandatho eziyindilinga ezenziwe nge-aluminium oxide. Efomini layo elicwengekile (elimhlophe), elibizwa nge-diamantine, i-aluminium oxide isetshenziswa njengepholishi eliphakeme kakhulu ekulikeni nasekubumbeni iwashi. I-Aluminium Oxide nayo isetshenziswa ekuhlanganisweni kwama-STACNIONS ku-Motor Cross nasezimbonini zebhayisekili ezintabeni. Le nhlanganisela ihlanganiswa ne-molybdenum disvuftate ukuhlinzeka ngokuthambisa isikhathi eside komhlaba.
