Hlau silicon yog dav siv nyob rau hauv refractory thiab hmoov metallurgy industries. Nws yog ib qho zoo heev antioxidant. Ntxiv metallic silicon rau hauv refractory tuaj yeem ua ntej ua pa nrog oxygen los tsim cov txheej txheem tshiab ntxhia, kaw qhov pores, txhim kho qhov ntom ntom thiab tiv thaiv kev nkag mus ntawm slag hlau, txhawm rau txhim kho qhov kub thiab txias, hnav tsis kam thiab oxidation tsis kam ntawm cov khoom. Yog li ntawd, nws yog dav siv nyob rau hauv cov ntaub ntawv refractory xws li steel-ua rauv, kiln thiab kiln rooj tog. Hauv kev lag luam metallurgical casting, metallic silicon yog siv los ua non-ferrous alloy additive thiab silicon steel alloy tus neeg sawv cev, txhawm rau txhim kho hardenability ntawm hlau. Hlau silicon kuj tseem siv tau los txo tus neeg sawv cev rau qee cov hlau thiab cov khoom siv ceramic tshiab.
