It is an amorphous silica product, with a primary particle size ranging from 7 to 40 nanometers, an aggregate particle size of approximately 200 to 500 nanometers, a specific surface area of 100 to 400m2/g, high purity, and a SiO2 content of no less than 99.8%. The surface untreated fumed silica aggregates contain various silanol groups.
