碱式碳酸锌前驱体合成纳米氧化锌及数据挖掘

Synthesis and data acquisition of nanocrystalline znic oxide from basic zinc carbonate precursor

以硫酸锌粉末与加有聚乙二醇-400为表面活性剂的碳酸钠粉末为原料,先经室温固相反应得到前驱体混合物,然后用水洗去混合物中的可溶性无机盐后将其烘干得到前驱体碱式碳酸锌,前驱体经350℃煅烧得到纳米氧化锌。基于均匀设计得到的数学模型,对试验的规律进行了数据挖掘的动态分析,明确获悉前驱体的煅烧温度还可以降低一些。

Using ZnSO4 · 7H2O and Na2CO3 containing surfactant PEG -400 as start materials, the precursor mixture was obtained by solid state reaction under room temperature,and then the basic zinc carbonate precursor was gained when the soluble inorganic salts were removed by washing with water and dried. Nanocrystalline ZnO was got by thermal decomposition of the precursor at 350 ℃. In this paper,basing on the mathematical model got from uniform design, dynamic analysis of data acquisition was done for experiment rules, and it was definitely learned that the temperature of thermal decomposition of the precursor could been reduced to some extent.
