The thermal decomposition of potassium, rubidium and caesium permanganates were investigated using TG and DTA techniques in atmospheres of air, oxygen, nitrogen and carbon dioxide. The studies were extended to cover related compounds, namely K2MnO4 and NaKMnO4. It is proposed that the two decomposition processes advanced by Herbstein and Boldyrev, respectively, take place simultaneously. The thermal decomposition of KMnO4 consists experimentally of two stages. The thermal decompositions of KMnO4 and K2MnO4 (also CsMnO4, RbMnO4, Cs2MnO4 and Rb2MnO4) are considered as redox reactions in which oxygen from the oxy-anions is oxidised to molecular oxygen, while the oxidation number of the manganese in the oxy-anion is either reduced by one in the oxy-anions concerned (e.g. from Mn(VII) to Mn(VI) in passage from MnO−4 or to MnO2–4 or to Mn(IV) in the “K4Mn7O16” phase.
