【Abstract】 Silicon dioxide is one of the most important padding for the rubber, plastic, dope and stickiness reagent all the while, because of its stability, reinforcing charactersitic, increasing density characteristic and thixotropy. Many kinds of preparation methods and processes for nanosized silicon dioxide will be introduced in this paper, and issues on disperse and drying in the process will be discussed deeply at the same time. The importance of application research on nanosized silicon dioxide and its facing problems are pointed out, and the runction of surface modification in improving the application of nanosized silicon dioxide is emphaxized.更多还原
