| Application scopes | Used as water reducing, stabilization of food, medicine, animal food and carrier, clarity assistance and the attach water reducing of essence and spicery. | |
| Features of products | Because of the sub-micron size and large BET of silicon dioxide, it can act as interval material between the granules of powder, at the same time; it also can improve the free flow of powder. Its water reducing feature can promote absorption and to prevent caking. Also can be used in medicine industry. | |
