Preparation of Small Size and High Total Cerium Carbonate AITranslate
Abstract AITranslate
Small size and high total cerium carbonate with the total >70 % and the particle size D50<15 μm was prepared by one-step precipitation using ammonium bicarbonate as precipitant.By using laser particle size analyzer,scanning electron microscope and EDTA titration methods,the effects of cerium chloride concentration,molar ratio of ammonium bicarbonate to cerium chloride,reaction temperature and pH value on the particle size and total of cerium carbonate were investigated.The results show that under the condition of cerium chloride concentration of 0.6~0.8 mol/L,molar ratio of ammonium bicarbonate to cerium chloride of 4 :1,reaction temperature of 80℃ and pH of 4,the precipitated cerium carbonate achieving good crystalline form,with particle size D50~15 μm and total >72M can be obtained.
