| Abstract: | The preparation of cerium carbonate product by cerium chloride and ammonium bicarbonate coprecipitation is studied ,high bulk density cerium oxide has been obtained through cerium carbonate high temperature roasting. Meanwhile,the ways of technology,the control of flow sheet and the effect of production are expounded,the result shows that it has low costs,small environmental pollution and bulk density of cerium oxide can be rised from 1.94 to 2. 10 g/cm^3. There is a good economic benefit. |
