Abstract: The thermoelectric properties of fine-grained alloys prepared by either cold pressing and sintering or hot pressing in the range 5-50 μm are compared with single-crystal best-direction values. It is shown that for the p-type alloy, almost the entire thermoelectric properties are recovered, i.e. the figure of merit for the finest grain size is almost the same as the best single-crystal value. The same trend is observed in the n-type alloy except that 90% of the single-crystal figure of merit is recovered
