Zirconia ua npuas ncauj ceramic lim yog tsim los ntawm ZrO2, nrog rau qhov kub thiab txias ntawm 1760 degree, muaj zog heev thiab zoo heev kub-kub tsis kam. Lub square zirconia ua npuas ncauj ceramic lim yog siv rau cov hlau castings, uas zoo tshem tawm impurities xws li slag thiab refractory fragments nyob rau hauv cov hlau molten, txhim kho cov nto zoo, txhua yam khoom thiab sab hauv cov qauv zoo ntawm cov hlau castings, thiab txo cov seem seem.
Hauv cov txheej txheem casting, zirconia ua npuas ncauj ceramic lim tuaj yeem ua rau cov hlau molten sau cov kab noj hniav kom sib npaug. Los ntawm cov qauv peb-dimensional ntawm zirconia ua npuas ncauj ceramic lim, turbulent flow yog hloov mus rau hauv ib qho kev ruaj khov laminar txaus, thiaj li paub txog cov qauv compact ntawm cov hlau casting, txhim kho qhov zoo ntawm cov hlau casting, txo qhov cuam tshuam thiab corrosion ntawm lub molten hlau nyob rau hauv lub casting kab noj hniav, thiab ntev kev pab cuam lub neej ntawm lub casting kab noj hniav.
