Silica gel desiccant abu ne mai matukar aiki na talla, wanda yawanci ana shirya shi ta hanyar amsa sodium silicate tare da sulfuric acid, tsufa, kumfa acid da kuma jerin hanyoyin magani. Silica gel abu ne mai amorphous, kuma tsarin sinadarai shine mSiO2. nH2O. Ba shi da narkewa a cikin ruwa da kowane irin ƙarfi, mara guba da rashin ɗanɗano, tare da kaddarorin sinadarai masu tsayayye, kuma baya amsawa da kowane abu sai tushe mai ƙarfi da hydrofluoric acid. Abubuwan sinadaran da tsarin jiki na gel silica sun ƙayyade cewa yana da halayen da yawancin sauran kayan aiki masu kama da wuya a maye gurbinsu. Silica gel desiccant yana da babban aikin adsorption, kyakkyawan kwanciyar hankali na thermal, kaddarorin sinadarai barga, ƙarfin injin, da sauransu.
