Figure 11.5.
Sections (r/t) of beech-based bioSiC, observed in scanning electron microscopy
using backscattered detectors, showing the distribution of SiC, Si, and C under increasing mag-
nifi cation (a), (b) and (c).
One of the advantages of the biomorphic SiC fabrication process, that make
it give total freedom to obtain complex shapes, is that the fi nal shape of the
ceramic parts is machined on the carbon perform (there is no shape change during
melt infi ltration). This net-shaped process involves a soft material in an inter-
