沉淀法制备纳米氧化锌的研究

Studies for Preparing Nanometer Size ZnO by Precipitation Method

通过实验和理论分析 ,对均匀沉淀法和直接沉淀法制备纳米氧化锌进行了比较 ,以硝酸锌为原料 ,尿素为均匀沉淀剂制得的氧化锌粒径小、分布窄、分散性好 ,远优于直接沉淀法制备的纳米氧化锌。

Based on experimental and theoretical analysis,homogeneous precipitation method is compared with direct precipitation method in producing nanometer size ZnO.Using zinc nitrate as raw materials and urea as precipitating agent,nanometer size ZnO produced by homogeneous precipitation method is well distributed,narrow dispersed and superior to ZnO produced by direct precipitation method.
