| titleOfInvention | Cerium Carbonate Manufacturing Method |
| abstract | The present invention provides a method for producing cerium carbonate through mixing and precipitation of cerium precursor and urea (Urea), (a) controlling the temperature of urea, or the temperature of both urea and cerium precursor to 50 ~ 150 ℃, respectively step; (b) introducing the urea and cerium precursors of (a) into a continuous reactor. And it provides a cerium carbonate powder prepared by the above method.n n n In addition, the present invention is a cerium oxide powder prepared by firing the cerium carbonate powder; And it provides a CMP slurry comprising the cerium oxide powder as an abrasive.n n n The present invention not only can produce cerium carbonate in high yield through the precipitation reaction of cerium precursor and urea in a continuous reactor, but can also control the crystal structure of cerium carbonate. |
