What is Spark Plasma Sintering

California Nanotechnologies - Intro to Spark Plasma Sintering

Spark Plasma Sintering (SPS) is a sintering technique used to fabricate dense and homogeneous bulk materials from powders. It involves the application of pulsed direct current (DC) and uniaxial pressure to the powder within a die. The DC current passes through the powder and generates a plasma discharge between the particles, causing rapid heating and sintering. The SPS process typically takes place in a vacuum or controlled atmosphere environment to prevent oxidation and ensure purity. The temperature, pressure, and heating rate can be precisely controlled during the process, allowing for the fabrication of materials with unique microstructures and properties. SPS has found applications in a variety of fields, including materials science, nanotechnology, and engineering. It is commonly used to fabricate ceramic, metallic, and composite materials with high density, fine grain size, and enhanced mechanical, electrical, and thermal properties. SPS has several advantages over traditional sintering methods, such as high heating rates, short processing times, and low sintering temperatures. These advantages result in reduced energy consumption and cost, improved material properties, and increased efficiency in the manufacturing process.
