Silicon dioxide yog ib qho tseem ceeb ntawm cov iav, quartz iav, dej iav, optical fiber, hluav taws xob kev lag luam, cov cuab yeej hluav taws xob, cov khoom siv tes thiab cov ntaub ntawv refractory raw cov ntaub ntawv, yog cov khoom siv tseem ceeb rau kev tshawb fawb.
Thaum silica crystallizes zoo kawg nkaus nws yog siv lead ua; Silica gel oxidation tom qab lub cev qhuav dej yog agate; Thaum lub aqueous colloids ntawm silica solidify, lawv ua opals; Thaum silica nplej muaj tsawg dua li ob peb microns, nws tsim chalcedony, flint, thiab quartzite. ib qho chaw muaj ntxhia nrog lub cev thiab tshuaj lom neeg ruaj khov. Lub iav siv los ua oxide ntxhia ntawm lub pob zeb ua rau muaj qhov nruab nrab, uas yog qhov kub tsis sib luag (-quartz), uas yog cov faib ntau tshaj plaws cov tsiaj ntxhia hauv quartz tsev neeg. ) .Quartz block kuj hu ua silica, feem ntau rau kev tsim cov xuab zeb quartz (tseem hu ua silica sand) cov ntaub ntawv raw, tseem yog quartz refractories thiab rho tawm cov khoom siv silicon hlau raw cov ntaub ntawv.
Tsis tas li ntawd, silica kuj tseem siv tau los ua cov roj nplua nyeem, yog qhov zoo tshaj plaws ntws nce qib, feem ntau yog cov roj nplua nyeem, tiv thaiv cov nplaum, ntws pab cuam.Nws tshwj xeeb tshaj yog tsim rau kev ua kom cov roj thiab cov tshuaj rho tawm. Cov granule ua tau zoo fluidity thiab compressibility.Nws tseem tuaj yeem siv los ua kev pabcuam txaus hauv kev nias ncaj ncaj.Txawm tus neeg sawv cev tsis zoo, nws tuaj yeem txhim kho qhov fluidity ntawm hais, nce qhov ceev ntawm hais, nce lub hardness ntawm npaj ntsiav tshuaj, kom luv lub sijhawm ntawm kev tsis sib haum xeeb, thiab nce qhov kev daws teeb meem ntawm cov tshuaj.Qhov tsim cov tshuab granule, nws tuaj yeem siv cov khoom sab hauv los ua kom lub zog ruaj khov ntawm cov tshuaj. ua kua, tus neeg saib xyuas cov thooj.
