一种高纯超细四碱式硫酸铅产品及其制备方法
摘要：
本发明公开了一种高纯超细四碱式硫酸铅产品及其制备方法，其中高纯超细四碱式硫酸铅产品的纯度≥99％，最大粒径≤15μm，平均粒径≤10μm；所述高纯超细四碱式硫酸铅的n(PbO):n(SO3)值在4.94～5.06范围内。本发明因使用了适宜的催化剂和粒径控制剂，显著加快了氧化铅与硫酸的反应速率，有效控制了产品的粒径，可在较低的反应温度下与较短的反应时间里制得高纯超细四碱式硫酸铅产品。
摘要（英）：

The invention discloses a high-purity ultra-fine tetrabasic lead sulfate product and a preparation method thereof, wherein the purity of the high-purity ultra-fine tetrabasic lead sulfate product is greater than or equal to 99%, the maximum particle size is less than or equal to 15 microns, and the average particle size is less than or equal to 10 microns; and the n(PbO):n(SO3) value of the high-purity ultra-fine tetrabasic lead sulfate is 4.94-5.06. By using a suitable catalyst and a particle size control agent, the reaction rate of lead oxide with sulfuric acid is remarkably accelerated, theparticle size of the product is effectively controlled, and the high-purity ultra-fine tetrabasic lead sulfate product can be prepared at lower reaction temperature in shorter reaction time.
