Silicon dioxide, feem ntau hu ua silica, muaj ntau hom xws li fumed silica, precipitated silica, thiab colloidal silica, txhua tus muaj cov yam ntxwv tshwj xeeb uas tsim los rau kev siv hauv kev lag luam. Cov tshuaj inorganic no, muaj silicon thiab oxygen, muaj nqis rau nws qhov purity siab, thermal stability, thiab ntau yam ntxwv xws li thaj chaw loj thiab qhov loj me ntawm cov khoom me me.

Cov silica uas tau ua los ntawm cov tshuaj lom neeg hauv cov kua dej, pom muaj kev siv hauv kev lag luam khau, ntxiv kev ywj pheej thiab kev nplij siab rau cov khau hauv qab. Nws lub peev xwm nqus tau siab kuj ua rau nws yog ib qho khoom xyaw tseem ceeb hauv cov xim thiab cov txheej txheem, qhov twg nws ua haujlwm ua tus neeg sawv cev tuab, tiv thaiv kev sagging thiab txhim kho kev tswj hwm dej ntws. Hauv cov nplaum thiab cov sealants, nws ua rau viscosity thiab lub zog sib txuas, ua kom ntseeg tau tias muaj kev ua tau zoo hauv ntau yam xwm txheej ib puag ncig.

Hauv kev lag luam tshuaj pleev ib ce thiab kev saib xyuas tus kheej, silica ua haujlwm ua ib qho khoom nqus dej hauv cov khoom xws li hmoov ntsej muag thiab cov tshuaj deodorants, pab tswj cov roj thiab cov dej noo yam tsis ua rau khaus tawv nqaij. Nws qhov xwm txheej inert ua kom sib xws nrog lwm cov khoom xyaw, ua rau nws yog ib qho khoom siv muaj kev nyab xeeb thiab zoo.

Silicon dioxide txoj kev tiv taus kub thiab tshuaj lom neeg xeb ntxiv nthuav nws txoj kev siv hauv cov ntaub ntawv refractory, qhov twg nws pab txhawb rau kev ruaj khov ntawm cov ntaub thaiv qhov cub thiab kev rwb thaiv tsev kub. Nws qhov muaj ntau yam thiab muaj peev xwm tsim tau ruaj khov raws li kev thov niaj hnub rau cov ntaub ntawv zoo rau ib puag ncig, ua kom nws lub luag haujlwm ua lub hauv paus tseem ceeb thoob plaws ntau yam kev lag luam.
