| Abstract: | The influences of technic conditions of preparation, such as concentration of sodium silicate, concentration of vitriol, reaction temperature and cocurrent time were studied by orthogonal design experiment. It is indicated that BET specific surface area is most significant influenced by reaction temperature, and the sequence of influence level are concentration of sodium silicate, cocurrent time and concentration of vitriol. BET specific surface area is influenced very much by the interaction of concentration of sodium silicate and reaction temperature. |
| Keywords: | silica cocurrent method technic conditions specific surface area |
