Synthesis of barium titanium oxide from barium sulphate and anatase: Study of equimolar mixtures under different atmospheres

Abstract : 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/H2, two reactions are studied. A mechanism of barium titanium oxide synthesis in helium (or in air) is proposed.
