| 摘 要： | 用气流磨制备了2个具有超细粒度的海山富钴结壳标准物质MCPt-1和MCPt-2。原样先经球磨成74μm(-200目),再用气流磨进行超细加工。样品粒度采用激光粒度仪检测,用粒度分布图和特征粒度来表达测量结果。两个样品的平均粒度分别为1.8μm和1.5μm(约2 000目),是目前粒度最小的标准物质。文章介绍了用于超细加工的流化床式气流磨原理与方法,展示了样品加工后的粒度分析结果,对比了国内外超细标准物质的概况。最后讨论了当前关注样品加工的重要性、超细加工的问题及超细样品分析研究的意义。 |
| 关 键 词： | 标准物质 超细加工 气流磨 粒度分析与表征 |

| Abstract: | Two Co-rich seamount crust reference materials of MCPt-1 and MCPt-2 for platinum group elements(PGEs) with an ultra-fine particle size have been prepared by a jet mill.The raw samples of the reference materials were ground by a ball mill to 74 μm(-200 mesh) powder and then were further processed by a jet mill to ultra-fine size.After well-mixed,the particle size distribution of the samples were tested by a laser particle analyzer.The results of particle size analysis were expressed by the particle size distribution plot and specific particle size.The average particle size MCPt-1 and MCPt-2 were 1.8 μm and 1.5 μm(about 2000 mesh) respectively.The paper also introduced principle and application development of fluidized bed jet mill used in ultra-fine process in standard reference material preparation worldwide.Finally,the importance and problems in ultra-fine sample processing,the significance of ultra-fine sample analysis in scientific research were discussed. |
| Keywords: | reference material ultra-fine processing jet mill analysis and characterization of particle size |
