Silica gel desiccant inonyanya kushandiswa adsorption material, iyo inowanzogadzirirwa nekuita sodium silicate ne sulfuric acid, kuchembera, asidi bubble uye mutsara wemashure ekurapa maitiro. Silica gel chinhu chine amorphous, uye chimiro chayo chemakemikari ndeye mSiO2. nH2O. Haina kunyungudika mumvura uye chero inonyungudutsa, isiri-chepfu uye isinganakidze, ine yakagadzikana makemikari ehupfumi, uye haibatike nechero chinhu kunze kwehwaro hwakasimba uye hydrofluoric acid. Iyo kemikari kuumbwa uye chimiro chemuviri chesilica gel inoona kuti ine maitiro ayo akawanda zvimwe zvinhu zvakafanana zvakaoma kutsiva. Silica gel desiccant ine yakakwira adsorption performance, yakanaka thermal kugadzikana, yakagadzika kemikari zvivakwa, yakakwirira mechanical simba, nezvimwe.
