5 FAQs of fumed silica nano sio2 silicon dioxide amorphous silica hydrophilic fumed silica 200 with CAS7631-86-9

1. What is fumed silica (nano SiO2)?
Fumed silica is a fine white powder made of silicon dioxide. It is produced by burning silicon tetrachloride in a flame of hydrogen and oxygen. This method creates nanoscale particles with high purity. The product has a CAS number 7631-86-9. It is amorphous, meaning it lacks a crystalline structure. The particles are small and have a large surface area. This makes them useful in many industrial applications.

2. What are the main uses of hydrophilic fumed silica 200?
Hydrophilic fumed silica 200 works as a thickening agent. It improves texture in coatings, adhesives, and sealants. It prevents caking in powders like food additives or pharmaceuticals.
