The interface potential of microparticles in aqueous solution is an important factor for scale formation in a water piping. For application to scale prevention process, the influence of alternating electromagnetic field on the interface potentials of CaC0 3 particles in the solution was investigated. Using a suspension of CaC0 3 particles dispersed in an electrolytic solution, we measured zeta potential changes of the particles by imposition of weak alternating electromagnetic field at

It is considered to be due to the specific adsorption of anions in the solution on the particles interface by the effect of induced electric field.
