摘要：

A method of selective measurement of released oxygen and water during thermal treatment of MnO2 has been developed. It is shown that in inert medium up to 300°C the basic weight losses are due to water release, while above 300°C they are determined by oxygen evolution. Above 350°C MnO2 is thermodynamically unstable in inert atmosphere. The existence of characteristic temperatures, not exceeding 300°C, and corresponding to the different natures of the bonded water, is confirmed. The re-absorbed water after thermal treatment of MnO2 is of a nature similar to that contained in the untreated commercial material.
