I want to do sintering for YSZ (Y 8 mol%). Sintering temperature ranging from 1400 oC to 2000 oC. Which method is better, Plasma Activated Sintering (PAS) or Spark Plasma Sintering (SPS)?
PAS and SPS are the same thing (also pulsed electric current sintering, PECS, and field assisted sintering technique, FAST). What are you trying to do/make? 8-YSZ is readily sintered without this method.
