What is the main difference between meteorological silica and precipitation silica?
The difference between precipitated silica and fumed silica is that the process is different and the particle size is different. Precipitated silica belongs to the micron scale, and fumed silica belongs to the nanoscale. General silica (regardless of gas phase method or precipitation method) is hydrophilic, and hydrophobic silica is hydrophilic silica through surface modification, so that the surface of silica has hydrophobic groups and has hydrophobicity. .
