Description
erosil or fumed silica is a synthetic mineral produced through the process of burning and condensing pure silica.
Characteristics of fumed silica:
- It has very small and spherical particles. The particle size is usually in the range of nanometers.
- It has a very high specific surface area, which means it has a high surface-to-volume ratio.
- It has high absorbent properties and can absorb a lot of moisture and fat.
- It is non-porous and has no internal cavities.
- It is non-toxic and biocompatible.
- It has a high melting temperature, about 1600 degrees Celsius
