Abstract

A silicide-based alloy material and a device in which the silicide-based alloy material is used are disclosed. The silicide-based alloy material can reduce environmental impact and provide high thermoelectric FIGURE of merit at room temperature. Provided is a silicide-based alloy material comprising, as major components, silver, barium and silicon, wherein atomic ratios of elements that constitute the alloy material are as follows: 9 at %≤Ag/(Ag+Ba+Si)≤27 at %, 20 at %≤Ba/(Ag+Ba+Si)≤53 at %, and 37 at %≤Si/(Ag+Ba+Si)≤65 at %, where Ag represents a content of the silver, Ba represents a content of the barium and Si represents a content of the silicon, and the silicide-based alloy material has an average grain size of less than or equal to 20 μm.
