摘要
以石英粉、生石灰为原料,水热合成活性托勃莫来石;再由盐酸和活性托勃莫来石通过化学沉淀法制备高比表面积SiO2。研究了水热合成条件和化学沉淀条件对SiO2比表面积的影响,确定了最佳试验条件,探讨了制备机理。
The active tobermorite was synthesis from quartz powder and quicklime by hydrothermal method. The SiO2 powder with high specific surface area was prepared by active tobermorite and acid. The high specific surface area was controlled by condition of the hydrothermal synthesis and chemical precipitation. The optimum test conditions were determined. The mechanism of preparetion was discussed.
