    Sharaxaada Alaabta

    Isku dhafka kiimikada Silicon Dioxide, oo sidoo kale loo yaqaan silica (laga bilaabo silix Latin ah), waa oksaydh silikoon ah oo leh qaacidada kiimikada SiO2. Waxaa lagu yaqaanay adayga tan iyo wakhtiyadii hore. Silica waxaa inta badan laga helaa dabeecadda sida ciid ama quartz, iyo sidoo kale gidaarada unugyada diatoms.
    Silica waxaa lagu soo saaraa noocyo kala duwan oo ay ku jiraan quartz la isku daray, crystal, silica fumed (ama silica pyrogenic), silica kolloidal, jel silica, iyo aerogel.
    Silica waxaa loo adeegsadaa soo saarista muraayadaha daaqadaha, muraayadaha cabitaanka, dhalooyinka cabitaanka, iyo isticmaalyo kale oo badan. Inta badan fiilooyinka indhaha ee isgaarsiinta ayaa sidoo kale laga sameeyay silica. Waa alaabta aasaasiga ah ee ceramics badan oo cadcad sida alaabta dhoobada ah, alaabta dhagaxa ah, dhoobada, iyo sidoo kale sibidhka Portland ee warshadaha.
    Silica waa wax lagu daro caan ku ah soo saarista cuntooyinka, halkaas oo loo isticmaalo ugu horreyn sidii wakiilka socodka ee cuntooyinka budada ah, ama in lagu nuugo biyaha codsiyada hygroscopic. Waa qaybta aasaasiga ah ee dhulka diatomaceous kaas oo leh adeegyo badan oo u dhexeeya sifaynta ilaa xakamaynta cayayaanka. Sidoo kale waa qaybta aasaasiga ah ee dambaska bariiska oo loo isticmaalo, tusaale ahaan, sifaynta iyo soosaarka sibidhka.
    Filimada khafiifka ah ee silica ee ku koray wafers silikoon iyada oo loo marayo hababka oksaydhka kulaylka ayaa faa'iido u yeelan kara microelectronics, halkaas oo ay u dhaqmaan sida korantada korantada oo leh xasilloonida kiimikada sare. Codsiyada korantada, waxay ilaalin kartaa silikoonka, kharashka kaydka, xannibaadda hadda, iyo xitaa waxay u dhaqmi kartaa sidii waddo la xakameeyey si loo xaddido socodka hadda.
    Ageel-ku-saleysan silica ayaa loo adeegsaday dayaxgacmeedka Stardust si uu u ururiyo walxaha ka baxsan dhulka. Silica sidoo kale waxaa loo isticmaalaa soo saarista DNA iyo RNA sababtoo ah awoodda ay u leedahay in ay ku xidho asiidhyada nucleic-ka ee hoos yimaada joogitaanka chaotropes. Sida silica hydrophobic waxaa loo isticmaalaa sida qayb ka mid ah foamer. Qaab fuuqbax leh, waxaa loo isticmaalaa dawada cadayga sida xoqid adag si looga saaro huurada cadayga.
    Awoodeeda sida dib-u-soo-celinta, waxay faa'iido u leedahay qaabka fiber-ka sida dharka ilaalinta kulaylka heerkulka sare. Qurxinta, waxay faa'iido u leedahay sifooyinkeeda iftiinka iftiinka iyo nuujinta dabiiciga ah. Silica Colloidal waxaa loo isticmaalaa sida khamriga iyo wakiilka ganaaxa casiir. Alaabooyinka dawooyinka, silica waxay caawisaa socodka budada marka kiniinnada la sameeyo. Waxa kale oo loo isticmaalaa sidii xarun kor u qaadida kulaylka warshadaha bamka kulaylka isha dhulka.
