...The effects conform to literature data [ 3 , 4]. After being melted K2S2O7 undergoes a slow decomposition in a wide temperature range, with a maximum rate at 690 � C, according to the following balance equation:...
...The reaction is more difficult with ZnO, CdO, CuO and aluminium, iron, chromium or vanadium sesquioxides of stoichiometry M2O3 [2, 3 ]. There are also cases in which a reaction of an oxide with disulphate(VI) is accompanied by reduction, as in reaction with Pb3O4 where only PbSO4 is formed ....
