Spark Plasma Sintering System

Photo of Spark Plasma Sintering System 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


  • Maximum sintering temperature: 2400 ℃
  • Heating rate: 0-1000 ℃/min; cooling rate: 0-150 ℃/min
  • Uniaxial load: 0 to 100 kN
  • Direct current power supply : 4000 A
