摘　　要：研制了一种X射线能谱仪/波谱仪(EDS/WDS)校准用纯锰片锰元素含量标准物质,使用电子探针(EPMA)检验了纯锰片锰元素含量的均匀性和稳定性,采用电感耦合等离子体发射光谱仪(ICP-OES)和电感耦合等离子体质谱仪(ICP-MS)对标准物质锰元素含量(质量分数,%)进行了定值,评定了标准物质的不确定度。研究表明:纯锰片标准物质锰元素含量的均匀性、稳定性良好,锰元素含量标准值为99.48%,扩展不确定度为0.92%(k=2)。研制的EDS/WDS校准用纯锰片锰元素含量标准物质可满足EDS/WDS的校准需求,为我国科研界和产业界的锰元素分析提供技术支撑。A reference material of pure manganese flake for manganese content calibration in X-ray energy/wavelength dispersive spectrometers(EDS/WDS)was developed.The homogeneity and stability of manganese content in the pure manganese flake were examined using electron probe microanalysis(EPMA).The manganese content(mass fraction,%)of the reference material was determined using inductively coupled plasma optical emission spectrometry(ICP-OES)and inductively coupled plasma mass spectrometry(ICP-MS).The uncertainties of the reference material were evaluated.The results show that the pure manganese flake reference material exhibits good homogeneity and stability in manganese content.The certified value of manganese content in the reference material is 99.48%with an expanded uncertainty of 0.92%(k=2).The developed pure manganese flake reference material for EDS/WDS calibration can meet the calibration requirements of EDS/WDS and provide technical support for manganese element analysis in scientific research and industry in China.
