The aim of this paper is to find the patterns in forming the microstructure of cermet composites prepared via spark plasma sintering. The composites consist of grained thermoelectric bismuth telluride, Bi2Te3 (a matrix of the composite), and ferromagnetic filler) Ni or Fe). It was found that under spark plasma sintering, the filler inclusions are forming as locally-gradient shell–core inclusions (Ni@NiTe2 and Fe@FeTe2), which are randomly distributed inside the textured Bi2Te3 matrix. Main parameters of composites microstructure (texturing degree and inclusions size) are strongly dependent on filler content
