Ludox Colloidal Silica
Description
This
photograph
demonstrates
the
exceedingly
fine
particle
size
of
Ludox
colloidal
silica
, a
new
product
of the
DuPont
Company
. This
picture
was
taken
with an
electron
microscope
. The
magnification
is
25,000
diameters
. This
high
magnification
was
necessary
because
the
diameter
of the
average
particle
is
about
one
two
millionth
of an
inch
. The
fineness
of the
particles
can
be
readily
appreciated
by the
fact
that the
horizontal
line
at the
bottom
of the
picture
presents
one
twenty-five
thousandth
of an
inch
.
Corporate creator
E.I. du Pont Nemours & Company
