Iimpawu ezintlanu ze-high-purity alumina powder
1. Ukumelana neekhemikhali;
2. Ucoceko oluphezulu lwe-alumina, umxholo we-alumina mkhulu kune-99%;
3. Ukumelana nokushisa okuphezulu, ukusetyenziswa okuqhelekileyo kwi-1600 ℃, ixesha elifutshane le-1800 ℃;
4. Ukumelana nokubanda ngequbuliso kunye nobushushu, akukho lula ukugqabhuka;
5. Yamkela i-grouting kwaye inoxinaniso oluphezulu.
1. Ukusetyenziswa kwe-α-uhlobo lwe-alumina powder
Kwi-crystal lattice ye-α-uhlobo lwe-alumina powder, i-ion ye-oksijini ifakwe ngokusondeleyo kwi-hexagons, kwaye i-Al3 + isasazwa ngokulinganayo kwiziko lokulungelelanisa i-octahedral ejikelezwe yi-oxygen ion.I-lattice energy inkulu kakhulu, ngoko ke indawo yokunyibilika kunye neqondo lokubilisa liphezulu kakhulu.I-α-uhlobo lwe-oxidation I-Aluminiyam ayinyibiliki emanzini kunye ne-asidi.Ikwabizwa ngokuba yi-aluminium oxide kwishishini.Yimathiriyeli ekrwada esisiseko yokwenza i-aluminiyam yesinyithi;iphinda isetyenziswe ukwenza izitena ezahlukeneyo eziphikisayo, i-crucibles refractory, i-tubes refractory, kunye nezixhobo zokuvavanya ukushisa okuphezulu;inokusetyenziswa kwakhona njengeziqhumiso kunye nezithinteli zomlilo.Iiarhente, izihluzi, njl.;Ucoceko oluphezulu lwe-α-uhlobo lwe-alumina lukwayinto ekrwada yokuvelisa i-corundum eyenziweyo, irubhi yokwenziwa kunye nesafire;ikwasetyenziselwa ukuveliswa kweesekethe ezinkulu zanamhlanje ezihlanganisiweyo.
I-alumina esebenzayo inomthamo okhethiweyo we-adsorption werhasi, umphunga wamanzi kunye nokufuma okuthile kolwelo.Emva kokuba i-adsorption igcwele, inokuvuselelwa ngokufudumeza malunga ne-175-315 ° C ukususa amanzi.I-Adsorption kunye novuko lunokwenziwa ngamaxesha amaninzi.Ngaphandle kokusetyenziswa njenge-desiccant, inokuphinda ibhengeze umphunga we-oyile yokuthambisa kwi-oksijini engcolileyo, i-hydrogen, i-carbon dioxide, i-gesi yendalo, njl.
I-alumina powder iyona nto iphambili kwimveliso yeengots ze-aluminium.Ineempawu zokubhabha okukhanyayo, ukumanzi kakuhle, ukunyibilika lula kunye nokufunxa okuqinileyo kwefluorine.Ifanelekile ukuveliswa kwe-aluminium yensimbi nge-electrolysis yetyuwa etyhidiweyo.Kwakhona yinto ebalulekileyo ekrwada kwimveliso ye-corundum, i-ceramics kunye ne-refractories.
