Umyinge we-particle ye-silica evuthayo incinci, kwaye indawo yayo ethile inkulu (80 ukuya kwi-400m2 / g). Ubume bayo bangaphakathi buphantse bulungelelaniswe ngokusondeleyo{4}}nobume be-dimensional, kwaye akukho phantse maqela e-hydroxyl ngaphakathi kwamasuntswana. Ke ngoko, amasuntswana e-silica efumileyo ane-hygroscopicity ephantsi kunye ne-adsorption eyomeleleyo yomhlaba, enefuthe elihle kakhulu lokomeleza. Ikhompawundi yerabha eyomelezwe nge-silica evuthayo inokukhanya okubalaseleyo, kunye neempawu zayo zomatshini, iipropathi zombane kunye nokumelana nobushushu nazo zilungile.
Nangona kunjalo, i-backback yeyokuba i-silica eqhumayo iyabiza kakhulu, ithanda ukubhabha ngexesha lokulungiswa, kwaye inokubangela lula ukudubula-i-static. Ngoko ke, ukukhuselwa kwegesi ye-inert kufuneka kusetyenziswe ngaphakathi kwezixhobo zokusebenza.
