The optimum conditions of preparation were as fellows : the concentration of zinc sulfate solution of 1 . 8 - 2 . omol / l , the concentration of ammonium bicarbonate solution of 1 . 4 ~ 1 . 6mol / l , the time of ultrasonic radiation of 25 ~ 30min . iv . preparation of active zinc oxide by means of microwave radiation to calcine precursor of basic zinc carbonate firstly , and a mechanism on preparation of ultra - fine active zinc oxide by means of microwave radiation has been investigated emphatically as well as the effects on quality of ultra - fine active zinc oxide have been analyzed and discussed in detail , the time of microwave radiation was 7 ~ 16 min ; comparing microwave radiation calcining with conventional calcining , the calcining time of microwave radiation was one thirty to one twenty , the calcining time shortened hugely , energy consumption saved hugely , the quality of product improved 首次引入超声波辐射制备超细活性氧化锌前驱体碱式碳酸锌新技术，研究了超声波辐射制备前驱体碱式碳酸锌的机理，并分析和讨论了影响前驱体质量的各种因素，确定了最佳的前驱体制备条件为：硫酸锌浓度为1 . 8 2 . 0mol / l ，碳酸氢铵的浓度为1 . 4 1 . 6mol / l ，超声波辐射25 30min ； 4 、首次采用微波加热煅烧前驱体碱式碳酸锌制备超细活性氧化锌的新技术，研究了微波辐射加热煅烧前驱体制备超细活性氧化锌的机理，并分析和讨论了影响活性氧化锌质量的各种因素，确定了最佳的超细活性氧化锌制备条件为：微波加热煅烧时间为7 16min ，与传统煅烧方法相比，煅烧时间仅为传统的1 30 1 20 ，大大缩短煅烧时间，节省能耗，提高了煅烧产品的质量； 5 、完成了从锌浮渣中制备超细活性氧化锌的小试试验和扩大试验。
A innovative technology with independent property right of knowledge on preparation of ultra - fine active zinc oxide by comprehensive utilization of zinc dross has been investigated and developed in this paper . the whole flow of preparation of ultra - fine active zinc oxide by comprehensive utilization of zinc dross and pilot test has been completed systemically 本课题研究了从锌浮渣中制备超细活性氧化锌的新工艺，系统地完成了从锌浮渣制备超细活性氧化锌的全流程以及扩大试验研究，试验证明从锌浮渣中制备超细活性氧化锌是可行的。
