FUJI ELECTRONIC INDUSTRIAL Co., Ltd. or Fuji SPS of Japan are pioneers in Spark Plasma Sintering (SPS), with more than 30 years in the business and generally considered the best proven and trusted SPS manufacturer on the market.
Spark Plasma Sintering is a synthesis method for preparing dense materials from a powder. The process can be a straight sintering of the powder, but often involves synthesis reactions to create new materials in the process.
The method employs high current DC on/off pulses to the material involved in the procedure. This heats the sample while it is being exposed to a large axial pressure. With this method, samples close to 100 % of theoretical density can be achieved.
