The study focuses on the thermoelectric properties of the sintered {ital n}- and {ital p}-type Bi{sub 2}Te{sub 3} prepared by those powders, respectively. The shapes of the powder consist of a plate-like and spherical particles after breaking the ingots. The powder including mostly a plate-like one (coarse powder) showed the higher green density and sintered density, and higher Seebeck coefficient than that of the sintered pellet prepared from the fine particle less than 40 {mu}m (fine powder). Electrical- and thermal conductivity should be compromised by controlling the density, pores, and the textures of the sintered body. The microstructures are analyzed by scanning electron microscope (SEM), and thermoelectric properties are discussed with sintered density and their textures. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
