Cov teeb meem xav tau kev saib xyuas txhawm rau txhim kho lub toughness ntawm xim av corundum

Rau xim av corundum, qhov tseem ceeb yog kom muaj lub zog zoo, uas kuj yog ib qho tseem ceeb rau peb xaivxim av corundumcov khoom. Tab sis qhov tseeb, qhov toughness ntawm xim av corundum yog ncaj qha cuam tshuam rau ntau yam, thiaj li yuav xyuas kom meej qhov kev ua tau zoo ntawm no nam, peb yuav tsum xyuam xim rau dab tsi?

Tom qab kev tshawb fawb tob, nws pom tau tias qhov tawv tawv ntawm xim av corundum feem ntau cuam tshuam los ntawm cov hauv qab no, xws li ntau dhau ntawm silica hauv xim av corundum, yog li tsis yog txhua tus tuaj yeem khaws cia, ntawm qhov tsis sib xws, nws yuav hnov ​​​​mob nrog alumina, li no txo ​​cov toughness ntawm xim av corundum khoom. Qhov thib ob, nws muaj peev xwm hais tias cov sulfur cov ntsiab lus nyob rau hauv xim av corundum yog tsawg tshaj li tus qauv tus nqi, uas kuj yuav muaj kev cuam tshuam tsis zoo rau nws toughness.
Txog rau qhov kawg no, peb yuav tsum tau them sai sai rau cov ntsiab lus txhuas ntawm cov xim av corundum, vim hais tias feem ntau, qhov siab dua cov ntsiab lus aluminium, qhov zoo dua qhov toughness ntawm cov khoom. Tsis tas li ntawd, nws tseem yuav tsum tau them sai sai rau cov txheej txheem calcination ntawm corundum xim av, uas yuav tsum tau ua nruj me ntsis raws li qhov yuav tsum tau ua, txhawm rau tsim cov khoom lag luam raws li qhov yuav tsum tau ua.
