Metallic silicon hmoovtuaj yeem tov nrog lwm cov ntaub ntawv xws li alumina, magnesium oxide, thiab zirconium oxide los tsim cov ntaub ntawv refractory nrog cov khoom tshwj xeeb.
Piv txwv li, nws yog xim hlau silicon hmoov tuaj yeem muab ntxiv rau alumina los txhim kho nws cov thermal poob siab thiab ua rau nws cov refractoriness.
Ntxiv rau nws siv hauv cov ntawv thov refractory, cov hmoov hlau silicon hmoov kuj tseem siv los ua cov khoom siv raw rau kev tsim cov khoom siv refractory, xws li silicon nitride (Si3N4) thiab silicon oxynitride (SiAlON).
Cov hmoov hlau silicon feem ntau yog khaws cia hauv qhov chaw qhuav, txias kom tiv thaiv oxidation thiab kev ua haujlwm tsis zoo.
