5Introduction of Silica Gel
- Silica Gel is Granular,Vitreous,Porous from of
Silicon Dioxide made Synthetically from
Sodiumsilicate. - Silica Gel contains a nano-porous Silica
micro-structure, suspended inside a liquid. - Most applications of silica gel require it to be
dried, in which case it is called silica xerogel. - Silica xerogel is tough and hard.
- As a desiccant, it has an average Poresize of 2.4
nanometers and has a strong affinity for water
molecules. - Silica Gel is most commonly encountered in
everyday life as beads in a small (typically 2 x
3cm) paper packet. - In this from, it is used as a desiccant to
control local humidity to avoid spoilage or
degradation of some goods. - Silica gel packets usually bear warning for the
user not to eat contents.
6HISTORY
- silica gel was in existence as early as the 1640s
as a scientific curiosity. - It was used in World War I for the adsorption of
vapours and gases in gas mask canisters. - The synthetic route for producing silica gel was
patented by chemistry professor Walter A. Patrick
at Johns Hopkins University in 1918. - In World War II, silica gel was indispensable in
the war effort for keeping penicillin dry,
protecting military equipment from moisture
damage. - as a fluid cracking catalyst for the production
of high octane gasoline, and as a catalyst
support for the manufacture of butadiene from
ethanol, feedstock for the synthetic rubber
program.

8Slica Gel White
The silica gel white is a natural desiccant that
is produced from Silicon Dioxide after the
application of certain synthetic processes.
Non-Indicating Type Silica Gel Desiccant
9Silica Gel Blue
Silica gel blue is another option for controlling
moisture which is obtains cobalt chloride in it
also known as self-indicating type of silica
gel. We can identify silica gel being full of
moisture which can absorb a big amount of water
from internal surface area.
Indicating Type Silica Gel Desiccant
