| Abstract: | Soft-chemical
routes play an important role in preparation of nano-materials. In particular,
the combustion synthesis has emerged as a promising solution-chemistry route
for synthesizing a variety of oxide ceramics in the nano-crystalline form. In
this review article, the potential of this technique for preparation of a few
oxide ceramics viz. yttria, barium polytitanates, barium and strontium thorate,
strontium cerates powders has been presented. The role of process parameters in
controlling the powder characteristics has also been established. These powders
were characterized in terms of X-ray diffraction, surface area analysis,
electron microscopy and sinterability. This process was shown to be a simple
and cost effective, which results in the phase pure, nano-crystalline powders
having high surface area and better sinterability. These combustion-synthesized
sinter-active powders achieved near the theoretical density, while retaining
the fine grain microstructure. |
