摘要： 采用水解——微负压蒸氨方法，控制晶粒成核及生长的条件，从精制的碳酸铵锌溶液制备符合饲料添加剂要求的碱式碳酸锌。锌的析出率〉98．0％，产品主成分Zn〉57．5％，粒径〈200nm，松散密度0．1～0．25g／cm^3。

Abstract: The nucleating and growing condition of crystal grain was controlled by hydrolysis-negative micro-pressure ammonia distillation. The basic zinc carbonate meeting the requirement for feed supplement was prepared from refined zinc ammonium carbonate solution. The exhalation rate of zinc was higher than 98.0 %, the content of main component zinc in products was higher than 57.5 %, the particle diameter of products was smaller than 200 nm and their loose smut of wheat thickness was 0.1-0.25 g/cm^3.
