Ntau yam cuam tshuam rau kev hnav tsis kam ntawm alumina ceramic pob

Hauv tsab xov xwm no, peb tsuas yog qhia ntau yam uas cuam tshuam rau kev hnav tsis kam ntawm alumina ceramic pob.Alumina ceramic pob yog tam sim no feem ntau siv cov khoom lag luam siab ceramic, uas tau nyiam mloog vim lawv zoo hnav tsis kam, corrosion tsis kam, siab txhua yam muaj zog, thiab siab sib tsoo efficiency.Alumina ceramic pob yog siv dav hauv kev npaj ntawm cov nplaim nplaum hauv kev lag luam ceramic thiab kev tsim cov hmoov zoo hauv cov khoom siv hluav taws xob, tshuaj lom neeg, metallurgy, thee mine thiab lwm yam kev lag luam.

Alumina nws tus kheej yog cov khoom siv zoo heev. piv nrog rau lwm yam kev sib tsoo cov xov xwm, qhov nyuaj yog qhov siab thiab lub zog nqus tshwj xeeb loj.Qhov thauj khoom ntawm cov khoom yuav tsum tau av hauv tib lub sib tsoo lub cev tau nce, lub pob zeb yog ntom, qhov tshwj xeeb zoo , thiab lub caij nyoog ntawm kev sib tsoo lub pob thiab cov khoom siv zog tau nce., tuaj yeem txo lub sijhawm sib tsoo thiab txhim kho kev sib tsoo kom zoo dua.Thaum pom qhov no, hnav tsis kam yog qhov ntsuas tseem ceeb los ntsuas qhov zoo ntawm alumina ceramic pob, yog li dab tsi yog yam cuam tshuam uas hnav tsis kam ntawm alumina ceramic pob?

raw khoom:

α-Al 2 O {{{2}}: Raws li lub hauv paus ntawm cov khoom lag luam, alumina hmoov, cov khoom tseem ceeb ntawm alumina, yog qhov tseem ceeb tshaj plaws.Its kev coj dawb huv, hloov pauv hloov ntawm α-Al 2 O {{2}}, thiab qhov zoo ntawm cov hmoov txhua qhov cuam tshuam cov hnav tsis kam ntawm alumina ceramic pob.Ib lub ntsiab lus ntawm kev sib deev.Ua alumina ceramic pob uas nws lub ntsiab siv lead ua yog α-Al {{1 }} O {{{2}}, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov hmoov ua nrog cov kev ua txhaum zoo thiab qhov tsim nyog hloov pauv ntawm α-Al 2 O {{2}}. tus nqi muaj qhov cuam tshuam zoo rau qhov zoo ntawm alumina ceramic pob.Qhov kev hloov pauv ntawm α-Al 2 O {{2}} yog qhov siab, nws qhov kev kub calcination yog qhov siab, qhov nyuaj ntawm cov khoom zoo heev nce qhov teeb meem ntawm cov hmoov sib tsoo, thiab qhov kev ua si sintering yog qhov tsawg.Yog qhov ntsuas kub siab sintering nce ntxiv, tsis tsuas yog yuav nce nqi, tab sis kuj tseem qhov kev loj hlob ntawm cov nplej tsis zoo Ib qho microstructure raug tsim, tab sis kev hnav kuj txo qis.Yog tus nqi hloov pauv ntawm α-Al 2 O {{2}} tsawg, nws cov calcination kub kuj tsawg, lub hardness ntawm cov hmoov tsis muaj zog, qhov kev sib tsoo yog qhov yooj yim, thiab cov haujlwm sintering loj, tab sis cov khoom shrinks ntau nrog cov khoom siv hloov kho, ua rau muaj kev tawg thiab deformation ntawm cov khoom.

Lub particle loj ntawm alumina ceramic hmoov: finer hmoov nyob rau hauv tib tej yam kev mob, qhov loj dua qhov tshwj xeeb cheeb tsam thaj chaw, lub siab dua saum npoo dawb zog, ntau dua qhov sintering tsav quab yuam, thiab qis dua sintering kub.Qhov nruj me ntsis tswj qhov zoo ntawm α-Al 2 O 3 hmoov thiab lwm cov hmoov tshuaj nyob rau hauv ntau lawm yog ib qho yuam sij rau kev nkag siab txhua yam zoo ntawm alumina ceramic khoom.
