Kev ntsuam xyuas hluav taws kub ua haujlwm ntawm chrome corundum bricks

Los ntawm Al2O3-Cr2O3 binary theem daim duab kos duab, peb tuaj yeem pom tias Al2O3 thiab Cr2O3 tuaj yeem tsim cov tshuaj txuas ntxiv yam tsis muaj eutectic. Yog li ntawd, ntxiv Cr2O3 rau cov khoom siv high-purity corundum, tsis hais tus nqi ntxiv, yuav tsis tsuas yog txo qhov hluav taws kub ntawm cov khoom, tab sis yuav ua rau kom hluav taws kub ntawm cov khoom. Lub refractoriness (> 1790) thiab load softening kub (> 1700!) ntawm chrome corundum bricks yog zoo dua li high-purity corundum khoom.
