1.Amandla aphezulu oomatshini.Amandla aguquguqukayo wealumina porcelain iimveliso sinteredifikelela kwi-250MPa, kwaye leyo yeemveliso ezicinezelekileyo ifikelela kwi-500MPa.Okukhona i-alumina icocekile, kokukhona amandla aphezulu.Amandla anokugcinwa ukuya kuthi ga kwi-900 ° C kumaqondo obushushu aphezulu.Ukusebenzisa amandla oomatshini bei-aluminium porcelain, inokwenziwa kwiindawo zoomatshini ezifana ne-porcelain.Ukuqina kwe mohs yeiiseramikhi zealuminainokufikelela kwi-9, kwaye inokumelana nokunxiba okugqwesileyo, ngoko ke isetyenziswa kakhulu kwizixhobo zokuvelisa, iivalvu zebhola, amavili okusila, izikhonkwane zeceramic, iibheringi, njl.
I-2.Ukumelana okuphezulu, ukusebenza kakuhle kombane wokufakelwa kombane.Ubushushu begumbi ukumelanai-aluminium porcelainyi 1015 Ω · cm, kwaye amandla okufakelwa yi-15kV/mm.Ukusebenzisa i-insulation kunye namandla ayo, inokwenziwa kwi-substrate, i-socket, i-spark plug, i-shell shell kunye nokunye.
3.Ubunzima obuphezulu.I-aluminium porcelaini-mohs ubunzima be-9, kunye nokumelana nokugqwesa okugqwesileyo, ngoko isetyenziswa ngokubanzi kwizixhobo zokuvelisa, amavili okugaya, izixhobo zokusila, umzobo wokufa, ukufa kwe-extrusion, iibheringi njalo njalo.Ukuchaneka okuphezulu kunokufezekiswa ngesantya esiphezulu sokusika xa kusenziwa iinjini zeemoto kunye neenxalenye zeenqwelomoya usebenzisa izixhobo ze-alumina ceramic.
4.Indawo yokunyibilika ephezulu.Ukumelana nomhlwa kwe-alumina porcelain yi-2050 ℃, kwaye inokumelana kakuhle ne-Be, Sr, Ni, Al, V, Ta, Mn, Fe, Co kunye nezinye iintsimbi ezityhidiweyo.Ikwamelana kakhulu nokhukuliseko lwe-NaOH, iglasi kunye ne-slag.Ayidibanisi ne-Si, P, Sb kunye ne-Bi kwindawo engasebenziyo.Ke ngoko, inokusetyenziswa njengezinto eziphikisayo, ityhubhu yesithando somlilo, umzobo weglasi yomzobo weglasi, ibhola engenanto, ifayibha, isigqubuthelo sokhuselo se-thermocouple, njl.
5. Ukuzinza kweekhemikhali okugqwesileyo.Iisulfides ezininzi ezintsonkothileyo, iiphosphates, i-arsenides, i-chlorides, i-nitride, i-bromides, i-iodides, i-oxides, kunye ne-sulfuric, i-hydrochloric, i-nitric, kunye ne-hydrofluoric acids ayidibanisi ne-alumina.Ngoko ke, i-alumina inokwenziwa ibe yintsimbi ecocekileyo kunye ne-crystal eyodwa yokukhula kwe-crucible, amalungu omntu, amathambo okwenziwa njalo njalo.
6. Iimpawu zamehlo.I-aluminium porcelaininokwenziwa kwizinto ezibonakalayo (i-alumina ecacileyo ye-alumina), isibane somphunga wesodium, i-microwave fairing, i-infrared window, i-laser oscillation element, njl.
7.Lonic conductivity.I-aluminium porcelaininokusetyenziswa njengemathiriyeli yeseli yelanga kunye nemathiriyeli yebhetri.
