Silika inozivikanwawo sesilicone dioxide.Silica ine zvakasiyana-siyana zvekushandisa: kudzora viscosity yechigadzirwa, kuwedzera kuwanda, uye kuderedza kujekesa kwekugadzira.Inogonawo kushanda seabrasive.Pamusoro pezvo, inogona kuita semutakuri we emollients, uye inogona kushandiswa kugadzirisa ganda rekugadzira kunzwa.Spherical silica ine porous uye inonyudza zvakanyanya, iine masimba ekunyudza zvingangoita 1.5 times kurema kwayo.Chirevo chakajairika chinosanganiswa ne silica kutonga kwemafuta.Inowanikwa mune sunscreens, scrubs, uye zvakasiyana-siyana zvezvimwe zvekuchengetedza kweganda, mazamu, uye kugadzirira kwebvudzi.Yakave yakabudirira kushandiswa mu hypoallergenic uye allergy-yakaedzwa mafomu.
Silica (SiO2) (RI: 1.48) inocherwa kubva mumadhipoziti e diatomaceous akapfava choko-sedombo (keiselghur).Iri iboka rakakosha rekuwedzera pigments, iro rinoshandiswa mumhando dzakasiyana-siyana.Iwo anoshandiswa sechinhu chinofuratira kuderedza kupenya kwemajasi akajeka uye kupa shear thinning kuyerera zvivakwa kune majasi.Dzinodhura.
Silicon (IV) oxide, amorphous inoshandiswa sevatakuri, kushandiswa kwekubatsira, anti-caking uye mahara-kuyerera maajenti mukudya kwemhuka.Defoamer application senge pendi, chikafu, bepa, machira uye mamwe maindasitiri ekushandisa.Synthetic silicon dioxides inoshandiswa se rheology control agent mumapurasitiki.Inoshandiswawo kugadzira zvinonamira, sealants uye silicones.
Kugadzirwa kwegirazi, girazi remvura, refractories, abrasives, ceramics, enamels;decolorizing uye kuchenesa mafuta, petroleum zvigadzirwa, nezvimwewo;mukukwesha- nekukuya-compounds, ferrosilicon, molds for castings;se anticaking uye defoaming agent.
