| 摘 要： | 研究了湿法锑白的白度和光敏性。通过真空干燥试验研究，对样品进次了Ｘ射线衍射定量分析，首次发现真空干燥可以使湿法锑白发生晶型转变，由斜方晶体转变为立方晶体。在适宜条件下，其转变率可达９９．６％。转变为立方晶的锑白白度高且见光稳定，光敏性消失。

| Abstract: | The degree of whiteness and the sensitivity to light of Sb_2O_3 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 Sb_2O_3 prepared by hydrometallurgy method can be turned from prismatic form into cubic ones (about 99. 6%) under suitable conditions by heat treatment in vacuum. The cubic Sb_2O_3acquired has high whiteness and is stable to light, i. e. its photo-sensitivity disappeared. |
