摘　　要：采用氧氯化锆和碳酸钠为原料进行低温固相反应得到碱式碳酸锆钠前驱物,前驱物经过加稀盐酸和除杂后得到碱式碳酸锆。对球磨条件、调酸稳定pH值洗涤水量对产物粒度及杂质的影响进行探讨。结果表明:碱式碳酸锆粒度分布均匀,纯度高,活性好。A new method to prepare zirconium basic carbonate（ZBC）is described. The precursors of ZBC were syn thesized by solid state reaction of ZrOC12SH20 to Na2CO3. The effect of grinding, pH value for adding acid on crystal and impurity were also investigated. The result showed that the ZBC was of high purity, reactivity and even distribution.
