Sodium zirconium basic carbonate precursor is prepared using zirconyl chloride and sodium carbonate as raw materials by low-temperature solid-phase reaction. Zirconium basic carbonate is then produced by adding dilute hydrochloric acid and cleaning on the precursor. This paper studies the effects of milling time and milling speed on the product granularity by performing infrared spectroscopy on the zirconium basic carbonate. The effect of acid pH degree on the product impurity content is also studied. The results show that the average particle size of zirconium basic carbonate products is around 11 μm with characteristics of uniform particle size distribution, good dispersion, strong activity and high purity under the optimal technical conditions (zirconium beads milling, milling speed with 150 r/min, milling time for 2 h, acid pH value amounting to 3.9~4.1).
