The temperature dependence of magnetic susceptibility and thermogravimetry of antimony trioxide and antimony trisulphide specimens in relation to their method of preparation

Several samples of pure antimony trioxide and pure antimony trisulphide of various origins were investigated for the temperature dependence of their magnetic susceptibility for the first time. Numerous measurements have been carried out, comprising X-ray diffraction patterns, pycnometric density, thermogravimetric analysis and the temperature dependence of magnetic susceptibility. Results indicate that both antimony trioxide and antimony trisulphide specimens are diamagnetic. The origin or method of preparation of each material investigated had a consistent effect on the values of diamagnetic susceptibility obtained. This could be attributed to the degree of purity, grain size and crystal structure of the materials of various origins investigated.
