Paper Title:
Study on Factors Affecting Properties of Silica
  Abstract

Silica was prepared by precipitation method in the laboratory, and the factors which affect the performance of silica were evaluated. The results show that the reduction of concentration of base solution and reaction temperature and the increase of pH value could improve the specific surface area of precipitation silica. Specific surface area of silica prepared in laboratory is greater than which was prepared in production line and DBP absorption value and particle size are smaller than the latter. Drying process and drying methods have important influences on performance of precipitation silica. Mechanical pulverization could reduce the particle size of silica slightly and the stacking density obviously.
