Materials Modification Inc. has developed and patented a novel powder consolidation technique. This process is the result of several years of research in the area of powder consolidation, primarily in the area of submicron and nanomaterials. The advantages of the SPS-P2C technique are

  • Reduced processing temperatures,
  • Significant reduction in the consolidation time, (minutes versus hours).
  • Lower oxygen content in the final part,
  • Higher density,
  • Does not need precompaction or the use of canning devices,
  • Absence of sintering aids and additives

The SPS-P2C process can be applied to all kinds of metals, intermetallics, and quasiceramics. SPS-P2C machines are designed based on the desired sample size, shape and the type of material. MMI also offers to consolidate powders for customers on a for-fee basis. In addition the SPS-P2C machine can be used to reactively synthesize and form near net shaped parts or can be used to reactively join selected dissimilar materials.

Another major advantage of the SPS-P2C setup is that it can be used very successfully on micron sized powders as an alternative to Hip’ing or hot pressing.

The typical shapes that can be produced using this machine can range from cylinders to hollow tubes and circular/curved plates. We can also provide the above shapes in a range of sizes.
