Experimental Research on Basic Zinc Carbonate Used for ZnO PreparationLIU Ping, CHEN Changchun, LU Chunhua College of Materials Science and Engineering, Nanjing University of Technology, Nanjing 210009Abstract:Zn（NO3 ）2 and （NH4）2CO3 are used as the raw materials to prepare basic zinc carbonate precursor by the precipitation method, with aim to seeking a reasonably experimental condition. The X-ray diffraction（XRD）, thermal analysis（DSC-TG） and scanning electron microscope（SEM） are used to characterize the structure and physical properties of the products. The experimental results indicate that the key factor for the fabrication of zinc carbonate is the rnol ratio between Zn（NO3 ）2 and （NH4）2CO3, and the optimal mol ratio is 1.5. In addition, the analysis results demonstrate that the main composition of basic zinc carbonate precursor is Zn4 CO3 （OH）6·H2O. After calcined in the muffle, the basic zinc carbonate precursor can be decomposed to crystalline ZnO ultra-fine particles,which have a hexagonal structure with the crystalline size between 20 and 50 nm.[著者文摘]
