Liquid suspensions and powders of cerium oxide particles, methods for their preparation and their use in polishing |
| abstract |
The present invention is characterized in that the average size of the particles (secondary particles) is 200 nm or less and the secondary particles comprise primary particles having an average size of 100 nm or less, wherein the standard deviation is 30% Lt; RTI ID = 0.0 > of < / RTI > cerium oxide particles. The suspension is prepared by contacting a solution of cerium-III salt containing cerium IV or hydrogen peroxide with a base in an inert atmosphere in the presence of nitrate ions. The resulting medium is then heat treated in an inert atmosphere and then acidified and washed. The suspension is dried and fired to obtain a powder. Suspensions and powders can be used for polishing. |
