Production of hydrophobic silica fine powder |
| 摘要 |
Hydrophobic silica fine powder is prepared by pyrolyzing a silane compound to give silica fine powder, then treating the silica fine powder with a hydrophobizing agent in a fluidization vessel containing at most 3 vol % of oxygen. The process effectively confers the pyrogenic silica with hydrophobicity.
