Synthesis of Barium Titanium-Oxide from Barium-Sulfate and Anatase - Study of Equimolar Mixtures Under Different Atmospheres
To enable the ceramization of a barium sulphate-rich radioactive waste the synthesis of barium titanium oxide is studied by using anatase and barium sulphate. As a function of the calcination atmosphere, helium (or air) and Ar/H-2, two reactions are studied. A mechanism of barium titanium oxide synthesis in helium (or in air) is proposed.
