Discover the exceptional qualities of our fumed silica, also known as fumed white carbon black. This product is ingeniously obtained through the high-temperature hydrolysis of chlorosilane in a hydrogen and oxygen flame. The result is a white, non-toxic, tasteless, and amorphous inorganic fine chemical product. By fine-tuning our process conditions, we produce fumed silica with primary particle sizes ranging from 7-40 nm and specific surface areas between 50-400m²/g.
| Model | Specific surface area (BET) | PH value of suspension (4%) | Burn loss (%) | Sieve residue (45um) (mg/kg) | Filling density (based on the product after drying at 105ºC for 2 h) (g/L) | Silica content (based on burnt product) (m/m%) | Carbon content (based on the product after drying at 105ºC for 2h) (m/m%) |
