Ultrafine silicon dioxide has attracted a great interest in the field of lubricating additives because of its excellent tribology performance. In this paper, the surface structure characteristic, the mechanism of surface modification and the general modification methods of ultrafine silicon dioxide were introduced, especially for alcohol/ester method, silane coupling agents method and surface grafting modification, and the more promising modification approach was indicated. In addition, the application of ultrafine silicon dioxide in lubricating oil was reviewed briefly. The future development trend of its application in lubricating oil was finally expected.
