text: If you are roasting sulfides, this is a very dirty and stinking process because sulphur is coming out as SO2 and the reaction heat also is not really high.\n\nYou may have a chance to use this compound as a pole of an electrode. But when I during my doctorate was doing experiments with antimony based electrodes, didn't come out attractive voltages.\n\nSo under normal circumstances (earthlife, oxigen in atmomsphere) I guess "NO".
