| 摘 要： | 以CuC12.2H2O,SnCl2.2H2O为原料,草酸为沉淀剂,采用共沉淀-热分解法制备Cu-Sn预合金粉末。采用X射线衍射仪(XRD)和扫描电子显微镜(SEM)分别分析前驱体粉末及热分解产物的物相组成和微观形貌,并研究所制备Cu-Sn预合金粉末的粒度和形貌特征。结果表明:共沉淀前驱体为CuC2O4.2H2O和SnC2O4.2H2O的固溶体,采用共沉淀-热分解法制备出的Cu-Sn预合金粉末具有粒度细小、粒度分布窄的特点,其中位径为1.68μm,且该合金粉末对前驱体粉末形貌具有继承性。

| Abstract: | Using CuC12.2H2O and SnCl2.2H2O as raw materials and H2C2O4.2H2O solution as precipitator,Cu-Sn prealloyed powder was fabricated by co-precipitation and thermal decomposition method.The composition and morphology of the prealloyed powder were characterized by X-ray diffraction(XRD) and scanning electronic microscope(SEM),the chemical composition and the distribution of the particle size was also analyzed.The results show that,the precursor was solid solution of CuC2O4.2H2 and SnC2O4.2H2O.The particle size o... |
