Silika imadziwikanso kuti silikoni dioxide.Silika ali ndi ntchito zosiyanasiyana: kulamulira mamasukidwe akayendedwe mankhwala, kuwonjezera chochulukira, ndi kuchepetsa chiphunzitso cha poyera.Itha kugwiranso ntchito ngati abrasive.Kuphatikiza apo, imatha kukhala ngati chonyamulira ma emollients, ndipo itha kugwiritsidwa ntchito kukonza mawonekedwe akhungu.Silika yozungulira imakhala ndi porous komanso imayamwa kwambiri, ndipo imatha kuyamwa pafupifupi 1.5 kulemera kwake.Zomwe zimagwirizanitsidwa ndi silika ndikuwongolera mafuta.Amapezeka m'ma sunscreens, scrubs, ndi mitundu yambiri ya chisamaliro cha khungu, zodzoladzola, ndi kukonzekera tsitsi.Zakhala zikugwiritsidwa ntchito bwino m'mapangidwe a hypoallergenic komanso oyezetsa.
Silika (SiO2) (RI: 1.48) amakumbidwa kuchokera ku miyala ya diatomaceous choko yofewa (keiselghur).Ili ndi gulu lofunikira la ma extender pigments, omwe amagwiritsidwa ntchito mumitundu yosiyanasiyana ya tinthu tating'onoting'ono.Amagwiritsidwa ntchito ngati chowongolera kuti achepetse kung'anima kwa zokutira zomveka bwino komanso kuti azitha kumeta ubweya wa ubweya ku zokutira.Iwo ndi okwera mtengo.
Silicon(IV) oxide, amorphous imagwiritsidwa ntchito ngati zonyamulira, zothandizira kukonza, anti-caking ndi othandizira otaya madzi muzakudya zanyama.Ntchito za defoamer monga utoto, chakudya, mapepala, nsalu ndi ntchito zina zamafakitale.Synthetic silicon dioxides amagwiritsidwa ntchito ngati rheology control agent mu mapulasitiki.Amagwiritsidwanso ntchito kupanga zomatira, zosindikizira ndi silicones.
Kupanga magalasi, magalasi amadzi, ma refractories, abrasives, ceramics, enamels;decolorizing ndi kuyeretsa mafuta, mafuta a petroleum, etc.;mu scouring- ndi akupera-compounds, ferrosilicon, nkhungu kwa castings;monga anticaking ndi defoaming wothandizira.
