Taw qhia ：
silicon dioxide (tshuaj lom neeg cov tshuaj: lub SiO ₂) yog ib hom acidic oxides, cov pa roj ntuj li silicate (H ₂ the SiO ₃). Silicon dioxide yog ib qho ntawm cov tseem ceeb tshaj plaws ntawm silicon. Lub ntuj silica hauv lub ntiaj teb tso tawm txog 12% ntawm pawg ua' s pawg, thiab nws cov ntawv uas twb muaj lawm tuaj yeem raug faib ua crystalline thiab amorphous yam, suav hu ua silica.Nws tuaj yeem siv rau hauv roj hmab, iav, tshuaj pleev ib ce , kev lag luam khoom noj khoom haus.
