Fumed silica, also known as fumed white carbon black, is a high-quality, fine chemical product. Produced through the hydrolysis of chlorosilane at elevated temperatures in a hydrogen and oxygen flame, this white, non-toxic, tasteless, amorphous material boasts an impressive range of applications. By meticulously adjusting processing conditions, our fumed silica features primary particle sizes ranging from 7 to 40 nm and a specific surface area 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%) |
