Field assisted sintering technology (FAST), also sometimes known as spark plasma sintering (SPS), uses a pulsed and/or continuous electric current along with the simultaneous application of compressive pressure which leads to extremely high heating rates

Field effects during consolidation of metallic powders

High electric current has been shown to enhance sintering kinetics during consolidation of many ceramic and metallic based powder materials using the process known as Electric Field Assisted Sintering (EFAS) or Spark Plasma Sintering (SPS). More recently, processes employing higher voltages and electric field strengths than these "current assisted" techniques have been shown to

Preparation of Highly Transparent Silica Glass by SPS

Abstract: Silica glass was prepared via the spark plasma sintering (SPS) method by using SBA-15 as the starting material. Five temperatures (1000, 1010, 1020, 1030 and 1040 C) were selected as the final sintering temperature above 600 C. [2] S.T. Selvan, T. Hayakawa, M. Nogami, Y. Kobayashi, L.M. Liz-Marzan, Y.
