Spark Plasma Sintering

Spark plasma sintering (SPS), also known as field assisted sintering technique or pulsed electric current sintering, or Plasma Pressure Compaction, is a sintering technique in which powdered sample can be sintered under uniaxial pressure.

The SPS at PARADIM is capable of operating at a temperature of 2500 °C with an option to provide Argon gas flow or vacuum. The applied Force can be varied between 1-60 kN. In an SPS, Joule heating plays a dominant role in the densification of powder compacts, which results in achieving near theoretical density at lower sintering temperature compared to conventional sintering techniques, enabling retaining of micro and nanostructures.
