Abstract

The phase diagram of the binary system of bismuth and antimony sesquioxides were investigated in the air atmosphere in the mole fractions of Bi2O3 between 0.000 and 0.500. Three different phase regions that were dependent onthe furnace temperature and heating period were obtained by the solid state reactions. In the first region, a heterogeneous mixture that contained orthorhombic Sb2O4 and monoclinic BiSbO4 phases occurred in the temperature range between 700 and 1100 degrees C. In the second region, the heterogeneous mixture transformed to a homogeneous solid solution that was characterised by a monoclinic crystal structure (BiSbO4 type). Fusion of the homogeneous solid solution which decomposed with volatilisation of Sb2O3 took place in the third region.
