Thermal separation of arsenic and antimony oxides

Experiments were carried out to remove arsenic from antimony trioxide by two techniques first by selectively volatilizing the more volatile arsenic trioxide from a mixed oxide sample and second by selectively condensing the less volatile antimony tetroxide at high temperatures leaving arsenic trioxide to condense out at a lower temperature. Thermodynamic analysis of the As-Sb-O system
