I-Hydrophilic Precipitated Silica
I-silica ye-precipitated iphinda yohlulwe ibe yi-silica yemveli ye-precipitated kunye ne-silica ekhethekileyo ye-precipitated. Owokuqala ubhekisela kwi-silica eveliswe nge-sulfuric acid, i-hydrochloric acid, i-CO2 kunye neglasi yamanzi njengesiseko sezinto ezisisiseko, ngelixa le yokugqibela ibhekisela kwi-silica eveliswa ngeendlela ezikhethekileyo ezifana nobuchwepheshe be-supergravity, indlela ye-sol-gel, indlela ye-crystal yekhemikhali, indlela ye-crystallization yesibini okanye i-reverse-phase micelle microemulsion method. -
