Optimizing

the

dispersion

of

carbon

nanostructures

in

ceramic

matrix

composites

is

a

fundamental

tech-
nological

challenge.

So

far

most

efforts

have

been

focused

on

improving

the

dispersion

of

nanostructures
during

the

powder

phase

processing,

due

to

the

limited

information

and

control

on

their

possible

redis-
tribution

during

the

sintering.

Here,

we

address

this

issue

by

comparing

multi-walled

carbon

nanotubes
reinforced

Si 3 N 4 composites

prepared

from

the

same

starting

powder

dispersion

but

sintered

using

two
different

techniques.

We

employ

ultra-small

angle

neutron

scattering

measurements

to

gain

reliable
information

on

the

dispersion

of

nanostructures

allowing

a

direct

comparison

of

their

redistribution
during

the

sintering.
