Fumed silica (commonly known as fumed white carbon black) obtained by hydrolysis of chlorosilane at high temperature in hydrogen and oxygen flame is a white, non-toxic, tasteless, amorphous inorganic fine chemical product. By adjusting the process conditions, fumed silica products with primary particle size between 7-40 nm and specific surface area between 50-400m2/g can be produced.
| 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%) |
| CT-200 | 200±30 | 3.7~4.5 | ≤2.5 | ≤250 | 40-60 | ≥99.8 | ≤0.2 |
Due to the characteristics of small particle size, large specific surface area and high surface activity, fumed silica has a wide range of applications in rubber, coatings, adhesives, paints, inks, plastics, cosmetics, agriculture, medicine and other fields, with good reinforcement, thickening, thixotropy, extinction, anti-ultraviolet, sterilization and other effects.
