【Abstract】 The vaporization of antimony trisulfide and antimony trioxide under puri fied Ar and of antimony trisulfide under At-O₂ mixture was investigated by weight loss method. The effects of temperature and oxygen pressure on vaporization were examined in detail. It is conisdered that chemical reactions on liquid surface seems to be the dominant factor in these processes, The mathematical models of vaporization rates have been obtained on the basis of some reasonable assumptions. The apparent activation energies of the chemical reactions in the vaporization have also been calculated.更多还原
