Fluoridové taveninové systémy pre zelenú výrobu hliníka bez produkcie CO2
Molten fluoride systems for green production of aluminium without CO2 emissions
Program: VEGA
Project leader: Ing. Šimko František, PhD.
Annotation: The proposed project is related to complex phase and physico-chemical analysis of multicomponent nMF-AlF3 systems (M = Na, K, n=3-1.2) with the addition of metal oxides Al, Fe, and Ni where compounds based on Fe and Ni are represented corrosion products from the use of inert anodes in aluminium CO2 less production. These are the so-called low-temperature electrolytes, whose research has recently increased attention related to the development and application of inert anodes. The aim of the project will be to define the solubility of oxides/spinels, the phase composition of the systems and to identify the individual components, arising from the interaction between the corrosion products and the electrolyte. These systems will be studied to determine the relationship between the structure and their physicochemical behavior by using either of spectral methods in-situ in the molten state, or by ex-post analysis of the solidified samples, and by physicochemical analysis of high temperature molten systems.
