Manganese Phosphide and Its Nano-Scale Applications

manganese phosphide is a coating used to enhance the performance of metal products. Typically, it is applied to steel parts for added strength and wear-resistance.

Unlike other metal finishes, manganese phosphide is not soluble in water and does not dissolve when exposed to liquid. This makes it a great choice for coating parts that are exposed to harsh environments, such as engine and transmission systems.

In addition to strengthening and protecting metal products, manganese phosphate can also be applied to improve electric conductivity and add resistance to the part’s surface. These characteristics are important for a variety of applications, such as automotive components, industrial tools, and more.

Nano-scale ferromagnetic manganese phosphide films and long rods have been successfully grown on GaP and glass substrates using a convenient one-pot vapor phase deposition method (STEM, TEM images). The films exhibit high ferromagnetic properties with a range of transition temperatures.

The morphology of the polycrystalline manganese phosphide films is controlled by the growth temperature and time. Increasing the growth temperature results in nucleation of secondary MnP crystals on the primary grains. These MnP crystals grow faster along the orthorhombic MnP c-axis, forming long rods that are readily detached from the substrates.

Compared with MnP/C and Mn2P/C, the MnP-Mn2P/C heterostructure was found to possess a higher binding energy per unit area for Li2S6 in Li-S batteries. This was attributed to the empty orbitals of Mn, which accept lone electron pairs from the Lewis bases. This allowed for the formation of coordination bonds between the ions, which then helped to anchor the polysulfide.
