Peb tsim ib puag ncig-phooj ywg magnesia-alumina-carbon cib, siv cov fused magnesia zoo, zoo fused corundum xuab zeb, zoo graphite ua cov khoom siv tseem ceeb. tshwj xeeb tshaj yog hloov cov ntaub ntawv pov tseg, siv cawv-raws li kev tiv thaiv ib puag ncig cob, ua kom kub hnyiab, ua rau cov khoom tsis muaj tshuaj lom thiab tsis qab, cov khoom lag luam hauv cov txheej txheem ci tom qab masonry, txhim kho ib puag ncig zoo, ua tiav qhov xav tau ntawm ib puag ncig zoo. Nyob rau tib lub sijhawm, cov khoom lag luam tau zoo dua qub, lub zog tau zoo dua qub, thiab qhov porosity tau txo qis heev. yog li ntawd, slag corrosion tsis kam thiab tiv taus xeb ntawm cov khoom tau txhim kho zoo heev, thiab kev pab lub neej ntawm cov khoom yog ntev dua li ntawm cov khoom sib raug zoo nrog cov khoom qub.
