A cermet material based on the system Ni–Al–SiO₂ with different SiO₂ weight content (0 – 50%) in the mixture was obtained by means of self-propagating high-temperature synthesis (SHS) with preliminary mechanoactivation (MA). It is shown that preliminary mechanoactivation of the powder mixture strongly affects the morphology of the final product. Depending on the composition of the initial mixture, the phases NiAl, Al₂O₃, Ni₂Si, and NiSi₂ can form in the final product of synthesis.
