Dioxyde ya Silicon |7631-86-9

Imiti ivangwa na Silicon Dioxide, izwi kandi nka silika (kuva muri silex yo mu kilatini), ni oxyde ya silicon hamwe na formulaire ya SiO2.Azwiho gukomera kuva kera.Silica ikunze kuboneka muri kamere nkumucanga cyangwa quartz, ndetse no murukuta rwa selile ya diatom.
Silica ikorwa muburyo butandukanye harimo na quartz yahujwe, kristu, silika yumye (cyangwa silika pyrogenic), silika ya siloidal, silika gel, na airgel.
Silica ikoreshwa cyane cyane mugukora ibirahuri kuri windows, ibirahure byo kunywa, amacupa y'ibinyobwa, nibindi byinshi bikoreshwa.Ubwinshi bwa fibre optique yo gutumanaho nayo ikozwe muri silika.Nibikoresho byibanze byibikoresho byinshi byera nkibikoresho byibumba, ibikoresho byamabuye, farufari, hamwe na sima ya Portland.
Silica ni inyongeramusaruro isanzwe mu gukora ibiryo, aho ikoreshwa cyane cyane nkibintu bitembera mu biribwa byifu, cyangwa kwinjiza amazi mubikorwa bya hygroscopique.Nibintu byambere bigize isi ya diatomaceous ifite byinshi ikoresha kuva kuyungurura kugeza kurwanya udukoko.Nibintu byibanze bigize umuceri husk ivu ikoreshwa, kurugero, mu kuyungurura no gukora sima.
Filime ntoya ya silika ikura kuri wafer ya silicon ikoresheje uburyo bwa okiside yumuriro irashobora kuba ingirakamaro cyane muri micrélectronics, aho ikora nka insulator zikoresha amashanyarazi kandi zifite imiti myinshi.Mubikoresho byamashanyarazi, birashobora kurinda silikoni, kubika ibicuruzwa, guhagarika imiyoboro, ndetse no gukora nkinzira igenzurwa kugirango igabanye umuvuduko.
Indege ishingiye kuri silika yakoreshejwe mu cyogajuru cya Stardust mu gukusanya uduce duto two ku isi.Silica ikoreshwa kandi mugukuramo ADN na RNA bitewe nubushobozi bwayo bwo guhuza aside nucleic imbere ya chaotropes.Nka hydrophobique silika ikoreshwa nkibigize defoamer.Muburyo bwa hydrated, bukoreshwa mumyanda yinyo nkikintu gikomeye cyo gukuraho amenyo.
Mubushobozi bwayo nkurunuka, ni ingirakamaro muburyo bwa fibre nkigitambara cyo hejuru yubushyuhe bwo hejuru.Mu kwisiga, ni ingirakamaro kumiterere-ikwirakwiza urumuri no kwinjirira bisanzwe.Siloidal silika ikoreshwa nka divayi n'umutobe ucuruza imitobe.Mu bicuruzwa bya farumasi, silika ifasha ifu itemba mugihe ibinini byakozwe.Ikoreshwa kandi nkibikoresho byongera ubushyuhe munganda zitanga ubushyuhe bwa pompe.
