Secondary fluorescence across phase boundaries is a difficult problem encountered in several electron probe microanalysis (EPMA) situations: diffusion couples; small phases enclosed in a larger phases; eutectic intergrowths; and thin films. In some cases, it is possible to construct nondiffused couples and to measure the amount of secondary fluorescence across the phase boundary, but in most ca...

These data and analyses support the research article "Experimental study on phase relations in the Ce-Fe-Sb ternary system" Zhu et al. (2017) [1]. The data and analyses presented here include the experimental results of XRD, SEM and EPMA for the determination of the whole liquidus projection and the isothermal section at 823 K in the Ce-Fe-Sb system. All the results enable the understanding of ...

In this paper we review the crystal chemistry and structure data from the literature and our results reported in the last decade for natural and synthetic samples of the tantalite-columbite series. Orderdisorder transitions and oxidation reactions on the ixiolite-columbite-wodginite system are reported for one Brazilian sample. It is shown that reports on these subjects are sometimes dubious an...

Measurements of highly radioactive actinides such as Np, Pu, Am, or Cm in as-fabricated irradiated nuclear fuels are crucial to improve the safety and performance fuel cycle, but also necessary find solutions environmental impact long-lived waste. Currently, most common technique measuring quantity distribution is electron probe microanalysis (EPMA). However, accurate analysis by EPMA accompani...
