Cov khoom ntawm magnesia alumina spinel cib
Magnesium aluminium cib muaj qhov zoo thermal shock stability thiab tuaj yeem tiv taus dej txias 20 mus rau 25 zaug, lossis ntau dua. Qhov no yog nws qhov zoo tshaj plaws kom zoo dua li cov magnesium cib zoo dua. Txoj kev tshawb no qhia tau hais tias MG-Al cib muaj zoo thermal shock stability, vim hais tias MG-Al spinel thiab cubic magnesite muaj nyob rau hauv lub cubic siv lead ua, thiab thermal expansion loj nyob rau hauv txhua lub axis siv lead ua yog tib yam, yog li thermal stress generated los ntawm expansion. thiab contraction kuj zoo ib yam thaum kub hloov pauv
Lub ntsiab kev ua tau zoo ntawm magnesia-aluminium cib kuj muaj zog me ntsis dua li ntawm magnesia-aluminium cib. Vim lub siab melting point ntawm magnesia-aluminium spinel nws tus kheej, load softening kub ntawm magnesia-aluminium cib yog zoo dua li ntawm magnesia-aluminium cib, ncav cuag 1620 ~ 1690C.
