銻的三種無定形硫化物在250°以內的差熱效應,曾於熱處理實驗、硫的提取實驗與粉末法的結果的配合下取得了鑑定與解釋.五硫化二銻與四硫化二銻在160°附近進行一放熱的、析出容易脫去的硫的析硫作用,並在220°附近進行無定形Sb2S3的晶化作用.

By heat treatment study, extraction experiments and powder photography, the differential thermal effects occuring below 250° of three amorphous sulfides of antimony are interpreted in this paper.At about 220°, all the three amorphous sulfides produce crystalline Sb2S3.In the neighborhood of 160°, the pentasulfide and tetrasulfide segregate into easily extractable sulfur and amorphous Sb2S3.
