Zusammenfassung:	PROBLEM TO BE SOLVED: To provide suspensions in which ion reaction causing flocculation of particles, increased suspension viscosity, shear thinning behavior and inhomogeneous agglomerate formation is suppressed. SOLUTION: Disclosed are suspensions having additives for controlled dispersion of particles comprising a solvent, an ion source, a particle source selected from a partially dissolving colloid or a non-dissolving colloid, and an additive wherein the additive is added to the solvent prior to the ion source and the particle source when the particle source comprises the partially dissolving colloid or added to the solvent within 24 hours after the ion source comprises the partially dissolving colloid.
