Abstract:The degree of whiteness and the sensitivity to light of Sb2O3 prepared by hydrometallurgy method have been studied. Through vacuum heat treatment experiments and X-ray diffraction quantitative measurement,it was first discovered that the crystal form of Sb2O3 prepared by hydrometallurgy method can be turned from pris-matic form into cubic ones (about 99. 6%)under suitable conditions by heat treatment in vacuum. The cubic Sb2O3 acquired has high whiteness and is stable to light，i. e. its photo-sensitivity disappeared.
Key words: whiteness sensitivity vacuum heat treatment antimony oxide
