The model 10-4 spark plasma sintering (SPS) system from Thermal Technology LLC introduces a revolutionary high-speed powder consolidation process. SPS utilizes high-amperage pulsed DC current to activate the consolidation and reaction-sintering of materials. SPS can sinter metallic or ceramic powders, or both, in a few minutes to a bulk sample with almost full density (diameter=10/20/40 mm, thickness=3-6 mm). Ideal for fast manufacturing of ceramics, alloys, composites, etc.
The key benefits of SPS include:
- Full density and controlled porosity
- Controlled grain growth: grain size can be retained at nanoscale
- Fast cycle time and low operating cost
- Energy and time saving
Manufacturing & Analysis
- Rapid densification of bulk nanomaterials from nano-size powders
- Preparation of advanced alloys (e.g. ODS alloys), metal-matrix composites (e.g.Cf/Al), and ceramic-matrix composites (e.g. SiCf/SiC)
- Sintering of ceramics (e.g. ZrB2, Ti2AlC) which are difficult to densify using conventional processing

- Heating rate: 0-1000 ℃/min; cooling rate: 0-150 ℃/min
- Uniaxial load: 0 to 100 kN
- Direct current power supply : 4000 A
