• Higher manganese silicide was produced using arc-melting and hot-pressing.
• The samples showed 10% texture with the c-axis aligned with the pressing direction.
• It was shown that ignoring the texture a 25% error in the ZT measurements can arise.
• The texture was shown to fit a model based on the general effective media approach.
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.
