Silica waxa kale oo loo yaqaan silicone dioxide.Silica waxa ay leedahay codsiyo kala duwan: si loo xakameeyo viscosity sheyga, ku dar bulk, iyo in la yareeyo hufnaanta qaabaynta.Waxa kale oo ay u shaqayn kartaa sidii abrasive.Intaa waxaa dheer, waxay u dhaqmi kartaa sida gudbiyaha emollients, waxaana laga yaabaa in loo isticmaalo si loo hagaajiyo dareenka maqaarka qaabaynta.Silica spherical waa dalool oo aad bay u nuugtaa, oo leh awood nuugista qiyaastii 1.5 jeer miisaankeeda.Sheegashada caadiga ah ee la xiriirta silica waa xakamaynta saliidda.Waxaa laga helaa muraayadaha qorraxda, xoqidda, iyo daryeelka maqaarka kale ee ballaaran, qurxinta, iyo diyaarinta daryeelka timaha.Waxaa si guul leh loogu isticmaalay qaab-dhismeedka hypoallergenic iyo kuwa la tijaabiyey xasaasiyadda.
Silica (SiO2) (RI: 1.48) waxaa laga qodo kaydka dhagaxa taamaashiirta u eg ee diatomaceous (keiselghur).Tani waa koox muhiim ah oo ka mid ah midabada fidsan, kaas oo loo isticmaalo qiyaaso kala duwan.Waxa loo istcimaalaa sidii walax fidsan si loo dhimo dhaldhalaalka dahaarka cad iyo in la siiyo sifooyinka qulqulka xiirid ee dahaarka.Waa qaali.
Silicon(IV) oxide, amorphous waxaa loo isticmaalaa sida sideyaal, qalabaynta qalabka, anti-caking iyo wakiilada socodka bilaashka ah ee quudinta xoolaha.Codsiyada foamer-ka sida rinjiga, cuntada, waraaqaha, dunta iyo codsiyada kale ee warshadaha.Silikoon ogsaydhyada synthetic waxaa loo isticmaalaa sidii wakiilka xakamaynta rheology ee balaastikada.Waxa kale oo loo isticmaalaa in lagu sameeyo xabagta, shaabadaynta iyo silikoonada.
Soo-saarka dhalada, dhalooyinka biyaha, refractories, abrasives, ceramics, dhaldhalaalka;midabaynta iyo nadiifinta saliidaha, batroolka, iwm;isku-darka-iyo-shiidida-isku-darka, ferrosilicon, caaryada wax shubidda;sida wakiilka ka-hortagga iyo wasakhaynta.
