I-Alpha-alumina ineempawu ezizinzileyo zeekhemikhali, ukuxhathisa ukubola, ubunzima obuphezulu, iipropathi ezilungileyo zokugquma, indawo ephezulu yokunyibilika kunye nokuqina okuphezulu, kwaye isetyenziswa kwiinkalo ezahlukeneyo.
Ukusetyenziswa kwe-α-alumina powder kwi-ceramics
I-Microcrystalline alumina ceramics luhlobo olutsha lwe-ceramic material kunye ne-uniform kunye nesakhiwo esixineneyo kunye ne-nano okanye i-sub-micron ubukhulu bengqolowa. Ineengenelo zamandla omatshini aphezulu, ukumelana nokunxiba, ukuxhathisa kwe-corrosion, ukumelana ne-oxidation, i-coefficient yokwandiswa okuhlengahlengiswayo kunye nokuzinza okuhle kwe-thermal. Inqaku layo eliphambili kukuba i-crystal ephambili incinci. Ngoko ke, eyona meko ibalulekileyo yezobugcisa ukulungiselela i-microcrystalline alumina ceramics kukulungiselela i-α-Al2O3 powder kunye nekristale encinci yasekuqaleni kunye nomsebenzi ophezulu we-sintering. Lo mgubo we-α-Al2O3 unokuba ngumzimba oshinyeneyo we-ceramic kwiqondo lobushushu elisezantsi.
Ukusetyenziswa kwe-α-alumina powder kwizinto eziphikisayo
I-α-Al2O3 powder ihluke kwizinto eziphikisayo ngokwesicelo, kwaye iimfuno ze powder nazo zihluke. Ngokomzekelo, ukuba ufuna ukukhawuleza ukuxinaniswa kwezinto eziphikisayo, i-nano-alumina iyona nto ikhethekileyo; ukuba ufuna ukulungisa iirefractories ezimile, udinga i-α-Al2O3 powder kunye neenkozo ezirhabaxa, ukuncipha okuncinci, kunye nokuchasana okunamandla kwe-deformation. I-Flake okanye iikristale ezimile njengepleyiti zingcono; kodwa ukuba i-amorphous refractory material, i-α-Al2O3 iyadingeka ukuba ibe ne-fluidity enhle, umsebenzi ophezulu we-sintering, kunye nokusabalalisa ubungakanani be-particle kufuna ubukhulu obukhulu be-bulk density, kunye ne-fine-grained crystallites ingcono.
Ukusetyenziswa kwe-α-alumina powder kwizinto zokupholisha
Izicelo zokupholisha ezahlukeneyo zifuna izixhobo ezahlukeneyo. Iimveliso zokupholisa ngokurhabaxa kunye nokupolisha okuphakathi zifuna amandla aqinileyo okusika kunye nobunzima obuphezulu, ngoko ke i-microstructure yazo kunye neekristale kufuneka zibe rhabaxa; I-α-alumina powder yokupholisa kakuhle ifuna ukuba imveliso epholisiweyo ibe noburhabaxa obuphantsi komhlaba kunye neglosi ephezulu Ke ngoko, incinci ikristale ephambili ye-α-Al2O3, ingcono.
Ukusetyenziswa kwe-α-alumina powder kwizinto zokuzalisa
Kwizinto zokuzalisa, ukwenzela ukuba kuqinisekiswe ukuba idibanisa kakuhle kunye ne-organic matter kunye nokunciphisa impembelelo kwi-viscosity yenkqubo, eyona mfuneko isisiseko ye-α-Al2O3 kukuba i-fluidity ilungile ngokwaneleyo, ngokufanelekileyo i-spherical, kuba iphakamileyo ye-sphericity, i-surface. Okukhona amandla amancinci, kokukhona angcono ukumanzi komphezulu webhola; okwesibini, i-alpha-Al2O3 powder kunye nophuhliso olupheleleyo lwekristale, ukucoceka kweekhemikhali eziphezulu kunye nomxhuzulane ochanekileyo ophezulu unomgangatho ongcono we-thermal conductivity kunye nesiphumo esingcono xa sisetyenziselwa i-insulating and thermally conductive materials.
Ukusetyenziswa kwe-α-alumina powder kwi-capacitor corundum material
Kumashishini, i-alpha-alumina powder ecocekileyo isoloko ifakwe kwisithando sombane esinobushushu obuphezulu ukwenza i-corundum eyenziweyo, eyaziwa ngokuba yi-corundum edibeneyo. Esi sixhobo sineempawu zobunzima obuphezulu, imiphetho ecacileyo kunye neekona, kwaye i-microstructure ikhethwa ngokufanelekileyo kufuphi ne-spherical. Kwinkqubo yokugaya isantya esiphezulu, iinkozo ezinqabileyo zinamandla okusika, kwaye iinkozo eziqhekezayo azilula ukuphuka.ngokwandisa ubomi bayo benkonzo.
