Sintered corundum cib yog cov khoom siv refractory feem ntau los ntawm high - purity alumina (al₂o₃) thiab raug rho tawm ntawm qhov kub. Lawv nthuav tawm zoo heev - cov khoom siv rigity, thiab cov tshuaj tsw qab (MoGE), chromium oxide (Cr₂o₃), lossis lwm yam kev sib ntxiv los txhim kho Sintering cov khoom lossis txhim kho kev ua haujlwm tshwj xeeb.) Hauv qab no yog cov ntsiab lus:

Cov yam ntxwv ua tau zoo
Vim yog lawv lub siab purity thiab tuab, siab {{purity alumina Clots ua rau cov khoom hauv qab no:
Kev ua siab ntev:Ntshiab Corundum muaj lub suab ntshiab li 2050 degree, thiab ntau dua muaj kev ua haujlwm siab tshaj li 1790 3}} lub sij hawm siv saum 1700oC.
Kev ua siab ntev hauv kev thauj khoom:Lawv tswj cov qauv kev ruaj ntseg hauv qab high - kub tawm thiab tiv taus deformation.
Lub zog siab: Possess high compressive strength (>100 MPa) thiab Flufal lub zog ntawm ob chav thiab kub siab, muab cov muaj zog tiv taus txhua yam kev ntxhov siab.
Zoo corrosion resistance:Ua kom pom zoo rau corrosion los ntawm kev sib tw ntawm Molten, Molten cov hlau, thiab molten iav, tshwj xeeb tshaj yog tawm tsam acidic thiab nruab nrab slags.
Hnav zoo heev:Ntev kev ntxhib los nrog zoo intergranular bonding, muab cov kev hnav zoo tshaj plaws.
Zoo Thermal poob siab:Muaj peev xwm nrog nrog kev nrawm thermal cycling.
Tsawg porosity thiab high bulk ntom ntom:Ua tib zoo sintered, nrog ob peb thiab uniformly faib interganular pores, uas yuav pab txhim kho lub zog thiab corrosion tsis kam.
Tsawg Thermal Condivity:Piv rau fused fused corundum cib, sintered corundum cib muaj qis dua thermal conductivity, muab zoo dua rwb los thaiv cov khoom ntiag tug.
Tshuaj lom neeg ruaj khov:Tsis yooj yim tawm tsam tshuaj lom neeg nrog ntau yam kev tshaj tawm ntawm cov kub.
Siab Purity:Feem ntau ua los ntawm high - purity alumina raw cov ntaub ntawv, xyuas cov khoom siv siab siab.
Tus qauv tuab:Tom qab high - kub sintering, ib ntom corundum, ib qho ntom corundum crystal nrog cov kev sib txuas lus zoo thiab cov porosity nyob hauv siab.
