Coj koj kom nkag siab cov yam ntxwv ntawm silicon cib refractory khoom
Qhov siab dua SiO2 cov ntsiab lus hauv cov khoom siv silica, qhov siab dua qhov refractoriness ntawm cov khoom. Cov impurities xws li K2O.Na2O yog teeb meem thiab yuav txo tau cov refractoriness ntawm refractory khoom. Fe2O3, CaO, MgO thiab lwm yam impurities ua lub luag haujlwm ntawm flux. Cov ntaub ntawv raw ntawm qib siab silicon bricks xav tau kev kho tshwj xeeb kom tshem tawm impurities.
Cov ntxhia muaj pes tsawg leeg ntawm silicon cib yog ib tug complex qauv ntawm squamous quartz, cristobalite, ib tug me me ntawm residual quartz thiab iav tsim nyob rau hauv high kub. Cov ntxhia muaj pes tsawg leeg fluctuates zoo heev raws li cov txheej txheem ntau lawm ntawm silicon cib thiab cov khoom siv raw khoom siv.
