Abstrakt: A study was made of the rheological and technological characteristics of suspensions. The presence of different types of flow is noted. We identified the influence of the phase composition on the nature of the rheological curves. We studied the rheological properties of calcium zirconate, and identified the optimum conditions for casting water suspension. The change in the rheological properties of the suspensions is interpreted from the viewpoint of the magnitude of hydration and kinetically bonded liquid. We demonstrated the link between the rheological properties of the heterophase suspensions and the change in ζ-potential. The change in the rheological properties of the suspension by means of small amounts of surface-active agents of the organic alcohol types in the optimum pH range makes it possible to obtain articles with outstanding properties, including those from compositions containing CaO right up to calcium zirconate.
