Spark Plasma Sintering / Field Assisted Sintering Technology




SPS allows for the rapid application of temperature and pressure via high-density pulsed current within a controlled atmosphere. The process is simple, repeatable, cost effective, and requires no previous sintering experience. SPS is the ideal consolidation method for most materials.

The Best for Academic / R&D to High Volume Full Production

SPS has the advantage of consolidating ceramic, metal and composite materials rapidly as compared to more lengthy conventional processes. Applications include thermoelectrics, aerospace, cutting tools, energy (turbine components, fuel cells), oil & gas, biomedical, and armor applications. SPS can provide fully dense forms (99% plus). The process rapidly consolidates nanomaterials, retaining the fine grain size. SPS is also used to produce functionally graded materials, as well as for bonding dissimilar materials.
