R-MnO2(e)

Product information

Manganese dioxide (MnO2) crystallizes into various phases, including R-type orthorhombic ramsdellite, α-type tetragonal hollandite, β-type rutile pyrolusite, λ-type cubic spinel, ε-type hexagonal, and γ-type nsutite (containing β- and ε-types as the intergrowths in R-type structure), etc. This variation in crystal structure gives rise to a variety of very intriguing physical and chemical functions. We supply a ramsdellite type MnO2 (space group: Pnma) powder as shown in Fig. 1.
