Because of the vay fast sintering rate, a sihca aerogel sample placed in a furnace in which the temperature is not homogeneous and varies between 9(X) and 1150°C will give rise to a graded porosity material Fig. 5-5). The top of the sample is Mly dense while the bottom maintains an opai porosity of 95%. Obviously a graded radial pore size distribution may also be obtained if a cylindrical sample is heated in such a way that its surface is at higher temperature than that of the core. [Pg.1277]

In this context, the aims of this study are to clarify the effect of different fast sintering techniques such as microwaves field at 2.45 GHz and external pulsed electrical field (Spark Plasma Sintering-SPS) on densification behavior of zirconia dispersed alumina nanopowders, on the microstructure and mechanic properties and to enhance the mechanical properties of the sintered composites.

The density of the ceramics obtained by FAST sintering is presented in Figure 8.3, compared with those obtained by conventional sintering. The phase content of the samples is presented in Table 8.1. It is noted that density close to the theoretical and almost full conversion to Al2TiOs (up to 92.5%) were achieved using FAST at 1050-1250 °C for 10 min. In the conventional sintering, formation of Al2TiOs occurs above 1300 °C and the density of the sintered samples represents about 70% of the theoretical one. [Pg.264]
