The traditional method to prepare silica uses sodium silicate, silicon tetrachloride and metasilicic acid as silicon materials; however, except for sodium silicate, the other two materials are very expensive, and the use of oil shale ash as a silicon material not only may greatly reduce the production cost of silica but also contribute to the comprehensive use of oil shale resources [17].
