The invention discloses a method of incorporating deagglomerated barium sulphate having an average primary particle size of less than 0.5 &#x3bc;m and coated with a dispersant into plastics or precursors of plastics, for example into polyols. The deagglomerated barium sulphate is dispersed in an organic solvent, the dispersion is incorporated into the plastic or the precursor of the plastic, and the solvent is evaporated off.

Method of generating a dispersion of deagglomerated barium sulphate in plastics or plastics precursors

Particles of strontium carbonate, barium carbonate, strontium sulfate and/or barium sulfate having a sufficient degree of fineness, especially when produced synthetically, are suitable as abrasive agents in chemical mechanical polishing (CMP polishing) of components, e.g., microelectronic components such as silicon wafers. The alkaline earth metal salt compounds are used as slurries in water and/or organic liquids and optionally may contain a dispersing agent, and preferably have a pH value of at least 8.
