A selective method has been suggested for the synthesis of highly dispersed powders of γ-WO3 (monoclinic) and β-WO3⋅H2O (orthorhombic) by the hydrothermal treatment of aqueous suspensions of peroxotungstic acid in temperature range 70–250°С.

The hydrothermal treatment of neutral and acidified KMnO4 solutions at concentration of 0.037–0.093 mol/L and temperature of 120, 170, and 220°С for 24 h leads to selective synthesis of three different manganese dioxide modifications: α-MnO2, δ

Thermal analysis was used to study the behavior of different cobalt oxides (CoO, Co2O3, and Co3O4) upon heating. At 200 – 850°C Co2O3 gradually transforms into Co3O4, which at about 920°C transforms into CoO. The effect of mechanical working in p
