| Abstract: |
| The silica with secondary particle structure was prepared by a two-step process，and its properties were investigated.The results showed that the silica exhibited amorphous structure，and it had good thermal stability；compared with traditional silica，the specific surface area of this silica was larger，the inner structure level was higher，the dispersibility was better，and the average diameter of particles and the aggregate size were smaller. |
