Abstract
Diffusion of sodium through MnO2 lattice in a high-temperature solid-state reaction can affect the original structure of manganese oxide. This effect is significantly concentration-dependent. For x < 0.5 in NaxMnO2, the chemical structure of sodium manganese oxide is accompanied by the formation of manganese oxide nanowires. The amount of such nanowires increases by increasing the concentration. For x > 0.5, it tends to form conventional layered structure (with microscale particles). In the case of MnO2, this phenomenon is only for Na diffusion, when a chemical structure corresponding to Na0.44MnO2 (JCPDS: 27-0750) is formed.
