Hydrophilic Precipitated Silica
Ua toe vaevaeina le silica fa'afefe i le silica fa'aleaga masani ma le silica fa'apitoa. O le mea muamua e faasino i le silica na gaosia i le sulfuric acid, hydrochloric acid, CO2 ma le vai tioata e avea ma mea masani, ae o le mea mulimuli e faasino i le silica na gaosia e auala faʻapitoa e pei o le supergravity technology, sol-gel method, chemical crystal method, second crystallization method or reversed-phase micelle microemulsion method. -
