Cov tshuaj tiv thaiv nrog dej thiab lwm yam khoom
Cov tshuaj reactivity ntawm ferrosilicon yog nyob ntawm nws cov muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov qauv. Cov tshuaj reactivity ntawm ferrosilicon nyob rau hauv aqueous xov xwm yog nyob ntawm ntau yam, xws li kub, pH thiab muaj impurities nyob rau hauv ob qho tib si dej thiab cov hlau nws tus kheej. Nyob rau hauv lub xub ntiag ntawm dej, ferrosilicon muaj ib tug hydrolysis cov tshuaj tiv thaiv nyob rau hauv nruab nrab los yog me ntsis acidic tej yam kev mob.
Cov txheej txheem no ua rau tsim cov roj hydrogen (H₂) thiab silicic acid (H₄SiO₄). Cov tshuaj tiv thaiv ntawm FeSi thiab 4H2O tsim Fe (OH) 2, H2 thiab H4SiO4.
Silicic acid yog cov kua qaub tsis muaj zog uas tuaj yeem ua rau muaj kev cuam tshuam ntxiv nrog cov dej molecules lossis lwm hom muaj nyob hauv cov tshuaj. Kev tso tawm cov pa roj hydrogen thaum lub sij hawm hydrolysis nthuav tawm qhov muaj peev xwm muaj kev nyab xeeb vim muaj kev pheej hmoo ntawm hluav taws. Tsis tas li ntawd, ferrosilicon qhia txog kev ua haujlwm ntawm cov kua qaub tshwj xeeb, suav nrog sulfuric acid, ntawm qhov kub siab. Hauv cov xwm txheej no, cov tshuaj tiv thaiv yog exothermic, uas ua rau tso tawm cov pa roj hydrogen thiab tsim cov hlau sulphates. Cov tshuaj tiv thaiv ntawm FeSi thiab H2SO4 tsim FeSO4, SiO2 thiab H2.
