Abstract
The present invention provides a process for producing an electrically conductive composition, such as an electrically conductive coating material, which is suitable for forming an electrode of an electronic element, in which the conductive powder is disintegrated into primary particles or near-primary particles and is satisfactorily dispersed in the composition. The conductive powder is disintegrated into primary particles or near-primary particles and is satisfactorily dispersed by either one of the following: a slurry containing an electrically conductive powder is pressurized and passed in branch flow paths,and,and the branch flows are unified at a collision chamber,; a single flow of slurry is caused to hit a collision wall; or the slurry is caused to pass through a narrow conduit rapidly so that the conductive powder undergoes a shear force.
