Cov nyhuv ntawm cov tshuaj tiv thaiv cov tshuaj tiv thaiv ntawm cov qauv thiab cov khoom ntawm MA-Al2O3 cov ntaub ntawv

Ob pawg ntawm MA-Al2O3Cov ntaub ntawv tau npaj los ntawm kev siv fused magnesia-aluminium spinel ua cov khoom siv tseem ceeb thiab ntxiv me me ntawm sintered corundum hmoov zoo es tsis txhob spinel hmoov zoo, los yog dawb corundum ua cov khoom siv tseem ceeb thiab ntxiv me me ntawm fused magnesia-aluminium spinel. hmoov zoo es tsis txhob dawb corundum hmoov zoo. Cov nyhuv ntawm cov tshuaj tiv thaiv ntawm corundum thiab MG-Al spinel ntawm cov khoom siv thiab microstructure tau kawm. Cov txiaj ntsig tau pom tias: 1) cov tshuaj tiv thaiv zoo tshwm sim nyob rau hauv ob pawg ntawm cov ntaub ntawv, uas ua rau kom cov aluminium-nplua nuj degree ntawm MG-Al spinel thiab nce cov ntsiab lus ntawm alumina (w) los ntawm txog 76% mus rau ntau tshaj 80%, yog li. ntxiv dag zog rau kev sib txuas ntawm cov qauv sib sau ua ke thiab cov matrix, txo cov qauv kev tsis xws luag, thiab txhim kho qhov kub thiab txias ntawm cov khoom siv; 2) Ntxiv sintered corundum rau MA-Al2O3 cov khoom siv nrog magnesia-aluminium spinel raws li cov khoom siv tseem ceeb tuaj yeem ua rau nws lub zog compressive ntawm chav tsev kub thiab txhim kho nws qhov kub thiab txias tsis kam thiab thermal shock resistance; 3) Nyob rau hauv cov dawb corundum raws li lub ntsiab raw khoom ntawm MA-Al2O3 khoom, ntxiv magnesium aluminium spinel hmoov zoo, nws chav tsev kub compressive zog, kub creep kuj thiab kub dabtsi yog khoov lub zog yog zoo heev.
