Deep Learning Methods for Elemental Map Prediction from MA-XRF spectra
Macro-XRF (MA-XRF) is a valuable non-destructive technique for investigating the chemical elemental composition of materials. MA-XRF data can be considered as high dimensional images, where a large vector of X-ray wavelengths emitted by excited atoms is computed for each pixel.

This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...
