Abstract: The microstructure, mechanical, and thermoelectric properties of samples of the n -type Bi_2Te_3–Bi_2Se_3 solid-solution samples containing 6, 8, and 10 mol % Bi_2Se_3, doped with antimony iodide, cadmium chloride, and hexabromobenzene, are investigated. The samples are formed by hot pressing and the extrusion of granules prepared by melt crystallization in a liquid and ground in a mortar, cutting mill, and ball mill. Measurements are performed at room temperature and in the range of 100–600 K. The formation conditions and compositions of materials with an ultimate compressive strength of ~250 MPa and thermoelectric efficiency of ( ZT )_max = (0.9–1.0) in the temperature range of 320–430 K are found.
