Abstract
Thermoelectric properties of directionally solidified B4C-TiB2 composites by a Floating Zone method were studied at temperatures from RT to 1023 K. The composition of TiB2 was changed between 0 and 25 mol% (eutectic composition). The difference of electrical conductivity (σ) and Seebeck coefficient (α) between parallel (∥) and perpendicular (⊥) to the growth direction were measured. At the eutectic composition, σ∥ was greater than σ⊥, and α⊥ was greater than α∥. Both α⊥ and α∥ showed the maximum around 2 mol%. The greatest power factor of 0.48×10-3 WK-2m-1 was obtained at 2 mol% in the perpendicular to the growth direction.
