Hydrophilic Precipitated Silica
Precipitated silica is further divided into traditional precipitated silica and special precipitated silica. The former refers to silica produced with sulfuric acid, hydrochloric acid, CO2 and water glass as the basic raw materials, while the latter refers to silica produced by special methods such as supergravity technology, sol-gel method, chemical crystal method, secondary crystallization method or reversed-phase micelle microemulsion method. -
Hydrophobic Fumed Silica
Fumed silica, or pyrogenic silica, colloidal silicon dioxide, is amorphous white inorganic powder which has high specific surface area, nano-scale primary particle size and a relatively high (among silica products) concentration of surface silanol groups. The properties of fumed silica can be chemically modified by reaction with these silanol groups. -
