Аннотация

Hydrothermal microwave treatment of mixed solutions of potassium permanganate and hexamethylenetetramine within the pH range 0.5–6.9, resulted in various polymorphs of nanocrystalline manganese dioxide: α-MnO2 (cryptomelane), γ-MnO2 (nsutite), β-MnO2 (pyrolusite), and δ-MnO2 (birnessite). The pH values of the medium at which single-phase samples form were determined.
