In addition, and very importantly, the surface chemistry of ceramic particles in suspension can be systematically altered to encourage the particles to arrange themselves in orderly, packing efficient configurations.
The above data is plotted in Fig. 5, whilst representative micrographs of the structures at three different points on the sintering curves, labeled a, b and c, are shown in Fig. 6.

The hematite a-Fe2O3 is one of the corundum structures and is an active catalyst for many important reactions like the dehydrogenation of ethyl benzene to styrene [6].
