Introduction to Spark Plasma Sintering Technology

CalNano, a leading distributor in the field of advanced manufacturing technology, specializes in providing state-of-the-art Spark Plasma Sintering (SPS) machines and equipment. This cutting-edge technology, also known as Field Assisted Sintering Technology (FAST) or Pulsed Electric Current Sintering (PECS), represents a significant advancement in the fabrication of high-density and high-strength materials.

How Does Spark Plasma Sintering Work?

SPS technology utilizes a combination of pulsed electric current and mechanical pressure to achieve sintering at remarkably low temperatures and short time frames compared to traditional methods. Here’s a breakdown of the process:

  1. Electric Current: The SPS machine applies a direct, pulsed electric current to a conductive die that houses the powder material. This current generates heat through the Joule effect, rapidly elevating the temperature of the material.
  2. Pressure Application: Concurrent with the electric heating, the machine applies significant mechanical pressure to the material, helping to densify it by closing gaps and eliminating pores.
  3. Sintering Mechanism: This simultaneous application of heat and pressure allows particles to bond more efficiently, producing materials with superior mechanical properties, minimal grain growth, and increased density.
