What is SPS ?

  • SPS is a pressure sintering technique such as Hot Press sintering (HP).
  • Powder or solid particles are filled in a mold typically made of graphite.
  • A direct current pulse is then applied to the mold and the powder inside under certain desired load.
  • The powder inside is heated by the self generated heat contrarely to conventional techniques in which the body is heated through the surounding atmosphere of the furnace.
  • In SPS, heat is confined to the powder or to the compound being sintered. There is no major loss of heat to the surrounding atmosphere such as in conventional sintering techniques.
  • SPS is energy saving sintering technique. SPS energy consumption is 1/3 to 1/5 of that used for sintering with conventional sintering techniques.
  • SPS is promising for fast heating as well as for fast cooling of sintered body. (several minutes instead of several hours in conventional techniques).
  • It is also promising for the densification of body structures.
  • It is promising for bonding of different kind of solid materials ( same or different kind metals to each other, metal to ceramic, etc..)
  • It is promising for sintering porous materials without changing pore size or pore structure.
