Fig. 6.10 Higher
magnification of one area of
the previous image, showing
fractures and detachments in
a side of the siliceous wall of
the diatom. Silica is a hard
and brittle material that is
difficult to section
( D. Badaut, EOST

Fig. 6.11 Bright-field TEM
image of a cross-section of
SiO 2 fibers (ceramic material)
embedded in a resin prepared
using ultramicrotomy,
showing: tearing of two fibers
that were partially ejected by
the diamond blade in cutting
because of their difference in
hardness with the embedding
resin ( D. Laub, EPFL-CIME,
Lausanne )
