Spark Plasma Sintering Services

SPS (aka FAST or Field Assisted Sintering Technology) allows for the rapid application of temperature and pressure via high-density pulsed current within a controlled atmosphere. SPS is the ideal consolidation and bonding method for all of your materials including metals, refractory alloys, nanomaterials, ultra-high temp ceramics, and more.

The team here at Cal Nano has over a decade of SPS experience sintering tens of thousands of samples with a wide variety of materials.

Cal Nano SPS/FAST Toll Services:

  • Collaborative R&D, prototyping and pilot-scale production services are available
  • High-quality customer service & quick turnaround times
  • Customers can provide powder or it can be sourced by Cal Nano
  • Sintering available in sizes from ranging from 10 mm to 6" OD

If interested in purchasing your own SPS equipment, please contact us for more information.

Cal Nano offers an array of unique capabilities for sintering or bonding your materials.

  • Sinter or bond your materials in minutes while minimizing grain growth and retaining complex microstructure
  • Most powders can be densified to 99%+
  • Rapid iteration testing of your materials - cycles can be completed in as a few minutes
  • Multiple inert atmosphere glove boxes for safe and effective powder handling
  • Controlled densification to create porous samples is also possible
  • Bonding of similar and dissimilar materials
  • Near net-shape sintering
