Dense, highly textured Z r B 2 and Z r B 2 – M o S i 2 ceramics were fabricated via a strong magnetic field alignment method followed by spark plasma sintering. Unlike with the previous studies, which only focused on the alignment of single‐phase particles, both Z r B 2 and M o S i 2 , which exhibited a magnetic anisotropy, have been aligned in this study. The alignment of M o S i 2 in the same direction of Z r B 2 enhanced the degree of orientation of Z r B 2 , decreased the grain size, but increased the aspect ratio of the platelet Z r B 2 grains. The microstructure and anisotropic mechanical properties as well as the oxidation resistance in different directions were discussed.
