The paper presents research results of the phase composition, crystal structure and hardness of AlMgB14-based ceramic materials obtained by the hot pressing method using powder mixtures of various grain-size composition. It is found that the largest amount of AlMgB14 phase of ~97 wt.% is achieved for the Al–Mg–B powder mixture after 4-hour activation in a planetary mill. The highest value of the hardness is detected as 31.9 GPa.
