Abstract: γ-MnO2 nanocrystalline was synthesized by hydrothermal method. XRD, TG,DTAand TEa were used to characterize the MnO2, nanocrystalline and its precursor. Theresults indicate that the powder obtained form crystallizing at 400℃ was γ-MnO2 with size inthe range of 5-10nm. When the powders were crystallized at 500℃, they agglomerated tobe spherical particles with a size about 50 nm. The thermal sensitivity of the MnO2nanocrystalline was also studied.

Key words: Nanocrystalline, γ-MnO2, Hydrothermal method, Thermal sensitive material
