    摘要： Aqueous dispersion comprising cerium oxide and silicon dioxide, obtainable by first mixing a cerium oxide starting dispersion and a silicon dioxide starting dispersion while stirring, and then dispersing at a shear rate of 10000 to 30000 s
    -1 , wherein a) the cerium oxide starting dispersion - contains 0.5 to 30% by weight of cerium oxide particles as the solid phase, - has a d5o of the particle size distribution of 10 to 100 nm - and has a pH of 1 to 7, and b) the silicon dioxide starting dispersion - contains 0.1 to 30% by weight of colloidal silicon dioxide particles as the solid phase, has a d5o of the particle size distribution of 3 to 50 nm and has a pH of 6 to 11.5, d) with the proviso that the d5o of the particle size distribution of the cerium oxide particles is greater than that of the silicon dioxide particles, the cerium oxide/silicon dioxide weight ratio is >1 and the amount of cerium oxide starting dispersion is such that the zeta potential of the dispersion is negative.
