text: could diantimony pentsulphide be the fuel of the future? what properties does it have?   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.  you 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.  so under normal circumstances (earthlife, oxigen in atmomsphere) i guess "no".
