Lub cev thiab tshuaj index ntawm silicon cib
Silicon cib yog cov khoom siv acid refractory, muaj zog tiv thaiv cov kua qaub slag los yog kua qaub yaj yaig muaj peev xwm, tab sis kev tiv thaiv rau alkaline tshuaj yaig tsis zoo, yooj yim rau kev puas tsuaj los ntawm Al203, K20, Na20 thiab lwm yam oxides, CaO, FeO, Fe2O3. thiab lwm yam oxides muaj kev tiv thaiv zoo.
Lub siab softening kub nyob rau hauv load yog cov yam ntxwv zoo ntawm silicon cib, feem ntau 1640 ~ 1680 degree, ze rau lub melting point ntawm squamite quartz (1670 degree) thiab cristobalite (1713 degree).
