Sintering is a method for making strong ceramic objects from ceramic powder.

  • Mixing water, binder, antiflocculant, and ceramic powder to form a slurry.
  • Spray drying the slurry
  • Putting the spray dryed powder into a mold and pressing it to form a green body (An unsintered ceramic material)
  • Heating the Green Body at low temperature to burn the binder off.
  • Sintering at a high temperature to fuse the ceramic particles together.

A similar process of sintering is sometimes used to form metallic objects. Sintered bronze in particular is frequently used as a material for bearings since it is porous and thus allows lubricants to flow through.

Sintering is related to Diffusion.
