Cov lus piav qhia luv luv:

Zirconium corundum yog smelted ntawm qhov kub siab nyob hauv hluav taws xob arc hluav taws xob nrog zircon xuab zeb ua cov khoom siv tseem ceeb. Nws muaj cov qauv tawv, compact qauv, siab zog thiab zoo thermal poob siab. Raws li cov kev ua kom tsis zoo, nws tuaj yeem tsim cov khoom ua tau zoo ntawm cov hnyav hnyav sib tsoo cov log, uas muaj qhov zoo sib tsoo ntawm cov hlau, cov hlau nrum, cov hlau tsis kam, thiab ntau yam khoom siv hlau; ntxiv rau, zirconium corundum tseem yog cov khoom lag luam refractory. Nws yog cov khoom siv zoo tshaj plaws rau cov kev ua haujlwm siab zawv zawg nozzles thiab tsis muaj lub zog ntxiv. Nws kuj tseem siv tau los ua zirconium corundum cib rau iav melting qhov cub.
