Fumed silica, also known as pyrogenic silica because it is produced in the flame, consists of microscopic amorphous silica droplets fused into branched, chain-like, three-dimensional secondary particles, which are then aggregated into tertiary particles. The resulting powder has an extremely low bulk density and high surface area.
Aerosil 200s three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickening or reinforcing filler.
Since it is a hydrophilic substance, it can absorb the water in its environment.

Amorphous Silica - Found in Earth's sediments and rocks. This is also the type that consists of sediments that accumulate over time in the sediments of rivers, streams, lakes and oceans.

General Description
Aerosil 200 occurs almost everywhere on earth.
Aerosil 200 is one of the most important and abundant oxides on earth, constituting about 60% weight of the earth’s crust as silica itself or in combination with other metal oxides in silicates.
Aerosil 200 commonly is found as sand in the vast ocean and river shores, their beds, deserts, rocks, and minerals.
Aerosil 200 exists in several structural forms: polymorphic crystalline silica, synthetic quartz crystals, amorphous silica, and vitreous silica. This classification is not complete as there are other forms of silica synthesized for specialized applications.
