A deflocculant added during wet milling acts to

  • A.bind the particles together into large granules
  • B.raise the firing temperature that is required
  • C.keep the particles separated in the suspension
  • D.increase the viscosity of the whole slurry

Answer: C

By giving the particles a like surface charge or a steric barrier it stops them flocculating, so a higher solids content can be handled at a workable viscosity. Sodium silicate and various polyacrylates are common choices.
