Silica ua lauiloa foi o le silicone dioxide. Silica e tele mea aoga: e pulea ai le viscosity o se oloa, faaopoopo le tele, ma faaitiitia le manino o se faiga.E mafai foi ona galue o se abrasive.E le gata i lea, e mafai ona galue o se ave mo emollients, ma e mafai ona faʻaaogaina e faʻaleleia ai le paʻu o le paʻu.O le silica spherical e porous ma sili ona mitiia, faatasi ai ma le mafai gafatia e tusa ma le 1.5 taimi lona mamafa.O se tagi masani e fesoʻotaʻi ma silica o le suauʻu pulea.E maua i le sunscreens, scrubs, ma le tele o isi tausiga o paʻu, teuga, ma sauniuniga o lauulu.Ua faʻaaogaina lelei i le hypoallergenic ma faʻataʻitaʻiga faʻataʻitaʻiga.
Silica (SiO2) (RI: 1.48) eliina mai le teuina o ma'a vaivai pei o penisina (keiselghur).O se vaega taua lea o pigments extender, lea e faʻaaogaina i ituaiga eseese o lapopoa.O lo'o fa'aaogaina e fai ma sui fa'apalapala e fa'aitiitia ai le iila o pa'u manino ma tu'u atu ai mea e fa'amama fa'amama fa'amama i pa'u.E fai si taugata.
Silicon (IV) oxide, amorphous e faʻaaogaina e avea ma ave, fesoasoani fesoasoani, anti-caking ma free-flow agents i meaʻai manu.Defoamer talosaga e pei o vali, meaai, pepa, ie ma isi alamanuia talosaga.Dioxide silikoni fa'akomepiuta o lo'o fa'aaogaina e fai ma sui e pulea le rheology i palasitika.E faʻaaogaina foi e gaosia ai mea faʻapipiʻi, faʻamaufaʻailoga ma silicones.
Gaosi tioata, ipu vai, refractories, abrasives, ceramics, enamels;suau'u fa'alenu'u ma fa'amamāina, mea tau suau'u, ma isi;i mea fa'afefiloi ma olo, ferrosilicon, molds mo fa'amea;e pei o le anticaking ma defoaming agent.
