This article presents the results of the high-temperature hydrolysis process of FeCl2×4H2O and the study of iron oxide powder properties produced. It is observed that the process has a topochemical character and proceeds in a diffusion zone. Conditions sufficient for practically complete decomposition of FeCl2×4H2O are a temperature in the range of 803–903 K and a duration of 40 minutes. The powder, obtained as a result of high-temperature hydrolysis of FeCl2×4H2O, is represented by an ultradisperse powder of iron oxides of 10–100 nm in size (average — 20 nm), having a basically round shape. The results of microprobe, X-ray phase analyzes, magnetic susceptibility analysis, and Mössbauer spectroscopy have revealed that the product of hightemperature hydrolysis consists of a mixture of iron oxides consisting of magnetite and hematite.
