    Abstract: A chemical and physical materials transformation reactor comprises reaction space enclosed by reactor housing (1) having two lateral fluid inlets (6) with adjustably mounted nozzles; and has fluid outlet (5) at bottom of reaction space, where exchangeable bottom plate (2) having hole as fluid outlet and on which moveably supported spheres are located to block the original path of fluid jets in unaligned state rests on the bottom of reaction space. Chemical and physical materials transformation reactor comprises reaction space enclosed by reactor housing (1) having two lateral fluid inlets (6) with adjustably mounted nozzles which include an angle of 20-160[deg] and through which fluid jets impinge on one another at a common collision point within the reaction space are passed. The reactor has fluid outlet (5) at bottom of reaction space, where exchangeable bottom plate (2) having hole as fluid outlet and on which moveably supported spheres are located to block the original path of fluid jets in unaligned state rests on the bottom of reaction space. A half shell (4) standing upright on the bottom of reaction space is located between each moveably supported sphere and wall of reactor space. The bottom plate, half shell and moveably supported spheres comprise hard materials.

    Abstract: Aqueous dispersion containing silicon dioxide powder, which is stable in a pH range of 2 to 6, which contains a cation-providing compound that is at least partially soluble in this pH range and the zeta potential of which is less than or equal to zero. It is produced by bringing silicon dioxide powder and at least one cation-providing compound into contact whilst moving in an aqueous medium. The dispersion can be used for chemical-mechanical polishing of metal surfaces.
