3.3. Rheological measurements
As shown in Fig. 4a and b the mechanical spectra of storage and
loss modulus (G
0
,G
00
), the temperature increase rate, the peak values
and the final setting values of G
0
under cooling were significantly
different among samples investigated and were strongly
dependent on particle size.
As temperature increased a viscous slurry was produced and
the structure changed from a viscous-like to solid-like, where G
