AEROSIL 200 FUME SILICA

AEROSIL 200 fume silica occurs almost everywhere on earth. 
AEROSIL 200 fume silica 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 fume silica commonly is found as sand in the vast ocean and river shores, their beds, deserts, rocks, and minerals.

MW:    60.08
EINECS:    231-545-4

AEROSIL 200 fume silica exists in several structural forms: polymorphic crystalline silica, synthetic quartz crystals, amorphous silica, and vitreous silica. 
AEROSIL 200 fume silica is not complete as there are other forms of silica synthesized for specialized applications.
AEROSIL 200 fume silica made up of linear triatomic molecules in which a silicon atom is covalently bonded to two oxygens.

With a unique range of both hydrophilic and hydrophobic grades available the number of applications are endless. 
AEROSIL 200 fume silica is composed of synthetic silicon dioxide (SiO2) which is entirely amorphous, eliminating the risks posed by crystalline silica.

One of the main applications for AEROSIL 200 fume silica is increasing the viscosity, pseudoplasticity and thixotropy of a wide range of liquid systems. 
However there are many more applications besides this common use case. 
AEROSIL 200 fume silica is the most extensive range of fumed silica on the market, with many of their products tailored for particular applications.

This results in improved free-flow properties even after extended storage. 
AEROSIL 200 fume silica can also be used as a thickening and stabilizing agents in bleaching creams.

In hair dyes, AEROSIL 200 fume silica prevents a premature reaction and caking of powdered colorant components.

In hair conditioners, hydrophilic AEROSIL 200 fume silica types such as AEROSIL 200 and AEROSIL 300, can help increase the volume of the hair, counteracting the “flattening” effect of the conditioning agents.

AEROSIL 200 fume silica, also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. 
The resulting powder has an extremely low bulk density and high surface area. 
AEROSIL 200 fume silica's three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.

AEROSIL 200 fume silica is another name for the chemical compound composed of silicon and oxygen with the chemical formula SiO2, or silicon dioxide. 
There are many forms of silica. 
All silica forms are identical in chemical composition, but have different atom arrangements. 
AEROSIL 200 fume silica can be divided into two groups, crystalline (or c-silica) and amorphous silica (a-silica or non-crystalline silica). 
AEROSIL 200 fume silica have structures with repeating patterns of silicon and oxygen. 
AEROSIL 200 fume silica chemical structures are more randomly linked when compared to c-silica. 
All forms of AEROSIL 200 fume silica are odorless solids composed of silicon and oxygen atoms. 
AEROSIL 200 fume silica particles become suspended in air and form non-explosive dusts. 
AEROSIL 200 fume silica may combine with other metallic elements and oxides to form silicates.
