Principle
Spark Plasma Sintering (SPS) is a rapid material preparation method that combines plasma activation, hot pressing, and resistance heating. It involves passing a pulse current directly through the mold and powder particles or bulk samples to induce sintering.
SPS utilizes the Joule heat generated by the current flow to heat the sample. The current passing through the powder creates spark discharge between adjacent particles, ionizing gas molecules and generating positrons and electrons. The resulting plasma purifies and activates the particle surfaces, promoting material migration and reducing sintering temperature and time.
The pulse current voltage applied provides high energy density, enabling rapid sintering and dispersion of the discharge point. This unique heating mode facilitates rapid cooling within the crystal structure, allowing for the preparation of high-quality amorphous and nano materials.
Advantages
- Rapid Sintering: SPS furnaces offer exceptionally fast heating rates, drastically reducing sintering time compared to traditional methods.
- Compact Structure: The compact design of SPS furnaces minimizes floor space requirements, enabling efficient deployment.
- Uniform Heating: SPS furnaces deliver uniform heating throughout the sample, ensuring consistent sintering results.
- High Heating Rate: The high heating rate of SPS furnaces enables rapid temperature increases, allowing for shorter processing times.
- Low Sintering Temperature: SPS furnaces operate at lower sintering temperatures than traditional methods, preserving material integrity.
- Surface Purification: The plasma discharge in SPS furnaces purifies the surface of particles, removing impurities and enhancing bonding.
- Grain Growth Inhibition: SPS furnaces minimize grain growth, resulting in a uniform and controllable product structure.
- Versatile Material Compatibility: SPS furnaces can sinter a wide range of materials, including metals, alloys, ceramics, and composites.
- Environmental Sustainability: SPS technology is environmentally friendly, reducing energy consumption and waste generation.
- Cost-Effectiveness: SPS furnaces offer a cost-effective solution for high-speed sintering, reducing production time and expenses.
- Solid-State Diffusion Bonding: SPS furnaces enable solid-state diffusion bonding between materials, providing high product strength and airtightness.
- Advanced Material Synthesis: SPS furnaces facilitate the synthesis of advanced materials, such as nanomaterials, functionally graded materials, and rare earth magnets.

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
