Qhov loj ntawm qhov hws loj ntawm Micropore Corundum Cib yog 20-8o, m, qhov loj me ntawm nruab nrab pores yog hais txog qhov tsis zoo 0.85 μ m, thiab r-inch quab yuam ntawm lub qhov hws me yog 0.003-0.006 μ M. Lub pore nkhaus ntsuas los ntawm mercury porometer txoj kev qhia tau hauv daim duab 7. Pore loj faib nyob ntawm CaO / SiOa piv. Yog tias CaO / SK ^ CL ntawm kev faib ua feem nyob hauv thaj tsam ntawm cms-mf-ma-m, tshwj xeeb tshaj yog thaj tsam ntawm 1325, muaj theem ua kua nyob hauv thaj chaw, tab sis tsis muaj qhov cuam tshuam loj ntawm cov txheej txheem sintering ntawm cov castable, thiab cov pores me me tseem muaj nyob. Thaum CaO / SiOa> 2, qhov nyiaj txhiag yog nyob rau hauv CA-ca-f (C4 AF) - mf-m thaj av. Tus nqi tsawg kawg ntawm kev sib cuag kaum ntawm periclase yog sib xws nrog cov kua theem ntawm kev tivthaiv. Hauv seem 14001, txawm hais tias muaj pes tsawg tus ua kua theem me dua li ntawm CaO / SiC ^ C ^, nws tau mus txog qhov tsawg kawg nkaus porosity thiab qhov tsawg kawg nkaus pore loj. Kev faib tawm ntawm lub qhov hws nyob ntawm seb qhov ntau ntawm cov khoom sib xyaw. Thaum cov khoom tawg zoo thiab microporous corundum cib muaj nyob rau tib lub sijhawm, cov qauv sib xyaw ua ke nrog cov txheej txheem tsis sib xws yog tsim, thiab cov txheej txheem sintering hauv zos uas ua rau txawv ntsws tuaj yeem ua tau. Vim tias tag nrho cov shrinkage tsis nyob hauv kev faib ua feem, qee qhov hws nrog qhov loj pore loj dua tias ua ntej sintering raug tsim tawm. Cov pores ntsws qeeb heev, thiab feem ntau ntawm lawv nyob twj ywm tom qab 20001 sintering. Txawm li cas los xij, qhov laj thawj ntawm pore txoj kev loj hlob tsis yog tsuas yog vim muaj kev faib ua feem, tab sis kuj yog vim muaj kev ntxhov siab ntawm qhov me me, vim hais tias nyob rau hauv cov ntaub ntawv ntawm cov tsis sib npaug ntawm cov feem me, qhov tshwm sim ntawm pore kev loj hlob tshwm sim thaum ua txhaum thiab siv.
Hauv qab lub tshuab tsom, cov qauv ntawm cov khoom lag luam magnesium feem ntau ua kom nrov, uas yog tus cwj pwm los ntawm cov caj ces tsis zoo. Sintered Micropore Corundum Cib zaj sib xyaw yog tsim los ntawm 0. (u-0.1mm) periclase polycrystal hais, uas yog cov txiv kab ntxwv daj thiab xim av daj, nyob ntawm seb puas muaj kev daws teeb meem ntawm magnesite& nrog rau qhov nce ntawm Duocheng kub (lossis kev pabcuam kub), cov periclase hais kom ntau ntxiv, thiab lawv yog li niaj zaus hexagonal. Thaum rhuab rau lub sijhawm ntev ntev ntawm qhov kub siab dua, qhov hais tawm Raws li qhov kev sib tsoo me me, cov khoom tawg tau tawg ua cov duab sib dhos. Nyob rau hauv qhov hws nruab nrab ntawm periclase hais, qhov nyiaj nyob ib ncig ntawm cov lus yog inlaid nrog silicate theem zaj duab xis. Cov theem silicate yog Ca Mg microalliorite [GG amp;].
Cov qauv ntawm MgO ^ 8% -> ntawm MgO microporous corundum cib yog tsim ntawm ib leeg ntawm cov kab xaim periclase, uas qhov kev tshem tawm ntawm impurity deposition pom. Ntxiv nrog rau castable, micro calcium thiab magnesium tseem muaj nyob hauv microporous corundum cib.
