“…The magnitude of the matrix effect varies by elements ratio in the mixture, resulting in the non-linear dependence of actual content that is clearly seen in Figure 8. Similar results for metallic powder mixtures containing Fe and Pb were observed by the authors [34,38]. It was noted that characteristic X-ray intensities of an analyte element in a composite sample might be positively or negatively affected by the chemical composition of the matrix.…”

“…The matrix effects are absorption and enhancement of other elements with far and near absorption edges on the analyte intensity. Such effect was described and investigated in several works [32][33][34][35][36][37][38]. In absorption factor, the matrix absorbs both primary X-rays and secondary analyte X-rays if the matrix may have a smaller absorption coefficient for the analyte line radiation.…”

The study is devoted to X-ray fluorescence spectroscopy (XRF) features of micro- and nanosized powder mixtures of copper and nickel. XRF is a high accuracy method that allows for both qualitative and quantitative analysis. However, the XRF measurement error due to the size of the studied particles is not usually taken into account, which limits the use of the method in some cases, such as analysis of Ni-Cu mixtures and coatings. In this paper, a method for obtaining copper and nickel nanoparticles was investigated, and the XRF of powder compositions was considered in detail. The initial micro- and nanoparticles of copper and nickel were studied in detail using SEM, TEM, XRD, and EDX. Based on experimental data, calibration curves for copper-nickel powder compositions of various sizes were developed. According to the results, it was experimentally established that the calibration curves constructed for nanoscale and microscale powders differ significantly. The presented approach can be expanded for other metals and particle sizes.
