Texture anisotropy of higher manganese silicide following arc-melting and hot-pressing Academic Article uri icon

abstract

  • In this research it is shown that thermoelectric higher manganese silicides (HMS) compounds produced by arc-melting followed by hot pressing exhibited textured behavior, due to the different number of Mn–Si bonds on the [00l] direction over the [hk0] direction, leading to ∼10% ZT enhancement in parallel to the pressing direction compared to the transverse direction. This shows that more carful considerations are required while assuming isotropic behavior in non-cubic polycrystalline thermoelectric materials.
