Field-assisted sintering technology/Spark plasma sintering is a low voltage, direct current (DC) pulsed current activated, pressure-assisted sintering, and synthesis technique, which has been widely applied for materials processing in the recent years . After a description of its working principles and historical background, mechanical, thermal
Spark plasma sintering (SPS), also known as field assisted sintering technique (FAST) or pulsed electric current sintering (PECS), is a sintering technique. The main characteristic of SPS is that the pulsed or unpulsed DC or AC current directly passes through the graphite die, as well as the powder compact, in case of conductive samples
Among other equipment are the VIS-300-01a microwave sintering system (Fig. 1) - a completely integrated computer controlled system with high temperature capability up to 2000°C and atmosphere control - and a Dr Sinter 515S spark plasma system from SPS Syntax

Spark Plasma Sintering is a new technique which takes only a few minutes to complete compared to conventional sintering which may take hours or even days for the same results. This high sintering rate is possible in SPS since high heating rates can be easily attained due to internal heating of the sample as opposed to external heating seen in
It is the fine quality that gets the laboratories from most of Chinese Science & Engineering Universities, and Scientific Research Institutes to use Chenhua vacuum furnaces to do the experiments. Main products as below: 1. Spark Plasma Sintering Furnace a. Mini Spark Plasma Sintering Furnace
2016627Pulsed electric current sintering (PECS) also known as spark plasma sintering (SPS) or field assisted sintering (FAST) is a relatively new innovative technique for the consolidation of fine or nanocrystalline powders and has received much attention in the recent years because of its many advantages compared with other sintering/bonding methods
thermal and electric ﬁeld evolution was assessed. During SPS, the heat transmission pattern and the temperature difference between the specimen center and the die surface depend on thermal conductivity of the powder compact, time of sintering and power input.
The annealed ingots were ground to powders with an agate mortar and then pressed using the spark plasma sintering (SPS-515S, SPS SYNTEX INC) method at 573-673 K and 50-100 MPa under vacuum for 5 min to form a dense pellet of 12.7 mm in diameter and 15 mm in height.
