SPS is also used for sintering of carbon nanotubes [11] for development of field electron emission electrodes. Functioning of SPS systems is schematically explained in a video link. [12] While the term "spark plasma sintering" is commonly used, the term is misleading since neither a spark nor a plasma is present in the process. [13]
Sintering cycle time for microwave sintering is much shorter as compared with the conventional sintering cycle. [8] Spark plasma sintering is a technique which takes only a few minutes to complete a sintering process compared to conventional sintering which may take hours or even days for the same. High sintering rate is possible in SPS since ...
For a number of years, it was speculated that the existence of sparks or plasma between particles could aid sintering; however, Hulbert and coworkers systematically proved that the electric parameters used during spark plasma sintering make it (highly) unlikely. [14] In light of this, the name "spark plasma sintering" has been rendered obsolete.

Moreover, sintering occurs via hot pressing (HP) or spark plasma sintering (SPS) [49] furnaces wich required mechanical prussere to produce a low porosity material [50], so the process allow to produce simple shape and scalability could be an issue.In addition, the consolidation of these materials is done combining a strong mechanical pressing ...

More advances in pressureless sintering must be made before it can be considered a viable method for UHTC processing. Spark plasma sintering is another method for the processing of UHTC materials. Spark plasma sintering often relies on slightly lower temperatures and significantly reduced processing times compared to hot pressing.
Spark plasma sintering (SPS) is a common name for this technique, however, it is technically incorrect since no spark and no plasma have been validated so far. Other common names for this technique are Direct Current Sintering, Rapid Hot Pressing, Direct Hot Pressing, amongst others.
