Silica fume yog qhov ua tau los ntawm kev tsim cov tshuaj silicon hlau lossis ferrosilicon alloys. Ib qho ntawm cov txiaj ntsig zoo siv rau silica fume yog nyob hauv cov pob zeb. Cov pob zeb ua muaj silica fume tuaj yeem muaj lub zog zoo heev thiab tuaj yeem ua ruaj khov.
Silica fume muaj feem ntau ntawm amorphous (tsis yog-crystalline) silicon dioxide (SiO 2). Cov kab mob feem ntau me me, kwv yees li 1 / 100 qhov luaj li cas ntawm cov khoom nruab nrab ntawm cov cement nruab nrab. Vim tias nws cov ntawv zoo, thaj tsam ntawm thaj chaw loj, thiab lub siab SiO 2 cov ntsiab lus, silica fume yog pozzolan cov tshuaj tiv thaiv zoo thaum siv rau pob zeb.
Txij li thaum lub sijhawm 1980 s, silica fume tau siv dav thoob plaws ntiaj teb los tsim cov pob zeb ua tau zoo. Niaj hnub no, ntau dua li 10 lab cubic meters ntawm cov pob zeb ua muaj silica fume muab tso rau txhua xyoo.
