ABSTRACT:
A method of controlling the adhesion of fine particles to an object in a solution characterized in that the adhesion of fine particles in the solution is prevented or reduced by adding into the solution a material, which is capable of controlling the zeta potential (surface potential) of the fine particles, in the amount of 10.sup.-7 to 25% by volume.
