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.
