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 17 and 18 and the branch flows are unified at a collision chamber 19; 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.
A process for producing an electrically conductive composition which comprises a first step of providing a slurry containing an electrically conductive powder and a second step of disintegrating and dispersing the conductive powder by at least one of causing collision of the conductive powder or applying a shear force to the powder, the slurry being in a pressurized state.
