Patent ID: 7861953

Claim:
A dispersing apparatus having a dispersing section that disperses agglomerated particles by applying a stress to the agglomerated particles, wherein the dispersing section has a structure through which a jet of a slurry containing the agglomerated particles passes to produce a tensile stress and in which the tensile stress acts on the agglomerated particles in the slurry to disperse the agglomerated particles; wherein the dispersing section includes a nozzle, a first cylindrical channel through which a jet stream produced through the nozzle passes, and a second cylindrical channel having a smaller cross section in a direction perpendicular to the jet stream than the first channel so that a tensile stress is produced when the jet stream coming through the first channel passes into the second channel, wherein the nozzle, the first channel, and the second channel are disposed in that order from the upstream side to the downstream side; and wherein a cross section, in the direction perpendicular to the jet stream, of the second channel is 1.0 to 1.57 times as large as a cross section, in the direction perpendicular to the jet stream, of the jet stream immediately before coming into the second channel.
