Using an electron microscope, carbon black can be seen to be a variety of
chained or cluster-like branched aggregates of approximately spherical primary
particles, with an overall diameter of 10-500 )im.
Specific surface area (m^ g ^). smaller primary particles have a larger specific
surface area. If it were possible to form a string of primary carbon black particles
