Silica izwi kandi nka dioxyde ya silicone.Silika ifite uburyo butandukanye: kugenzura ibicuruzwa byijimye, kongeramo byinshi, no kugabanya gukorera mu mucyo.Irashobora kandi gukora nkigisebo.Byongeye kandi, irashobora gukora nk'itwara rya emollients, kandi irashobora gukoreshwa mugutezimbere uruhu rwimitsi.Silika ya serefike irashashaye kandi ikurura cyane, hamwe nubushobozi bwo kwinjiza hafi inshuro 1.5 uburemere bwayo.Ikirego gisanzwe kijyanye na silika ni kugenzura amavuta.Iboneka mu zuba, izuba, hamwe nubundi buryo bwo kwita ku ruhu, kwisiga, no gutegura umusatsi.Byakoreshejwe neza muri hypoallergenic na allergie-yapimwe.
Silica (SiO2) (RI: 1.48) yacukuwe mu bubiko bwa diatomaceous yoroshye ya chalk imeze nk'urutare (keiselghur).Iri ni itsinda ryingenzi ryagura pigment, rikoreshwa mubunini butandukanye.Zikoreshwa nkibikoresho byo gusibanganya kugirango bigabanye ububengerane bwimyenda isobanutse no gutanga ibintu byogosha ibintu byoroshye.Birahenze cyane.
Okiside ya Silicon (IV), amorphous ikoreshwa nk'abatwara, imfashanyo zitunganya, anti-cake hamwe nubusa-bwisanzure mu kugaburira amatungo.Porogaramu ya Defoamer nk'irangi, ibiryo, impapuro, imyenda nibindi bikorwa byinganda.Dioxyde de sintetike ya silicon ikoreshwa nkibikoresho byo kugenzura imiterere ya plastiki.Ikoreshwa kandi mu gukora ibifatika, kashe na silicone.
Gukora ibirahuri, ikirahuri cyamazi, inganda, abrasives, ceramics, emamel;gushushanya no kweza amavuta, ibikomoka kuri peteroli, nibindi.;mugushakisha- no gusya-ibice, ferrosilicon, ibishushanyo byo gukina;nka anticaking and defoaming agent.
