A homogeneous mass of particulate manganese dioxide which has been heat-treated to reduce its moisture content and treated with an organic solvent which substantially fills the pores of the manganese dioxide thereby reducing its affinity for absorbing moisture when exposed to a moisture environment for a fixed time period. The invention also relates to a process for producing the manganese dioxide.
