METHODS OF SHAPE FORMING CERAMIC POWDERS
For example hot pressing of silicon carbide is carried out at temperature about 3630 ºF (2000ºC). Hot pressing permits obtaining better compaction, higher green compact density and higher (than in cold pressing) strength of the part. Die pressing is used for
Manufacturing Advanced Ceramics - International Syalons
Ceramics such as silicon nitride and silicon carbide are more difficult to densify and often use a sintering mechanism called liquid–phase sintering. In this case a small volume of additives in the mix form a liquid at sintering temperatures in which the primary powder particles (for example silicon nitride) firstly rearrange due to capillary forces, giving better packing.

Research into the warm compaction of metal powders - …
The technological method of warm powder compaction is similar to that of axial die compaction, except that both the powder and the die must be heated to a temperature between 100 and 160 C. This temperature range was chosen for two reasons, i.e.: at temperatures below 100°C the effect is negligible, as the phenomena accompanying compaction are identical to those accompanying cold compaction.
