The effect of the ratio of the components of mixtures of nickel (II) oxide with titanium on the modes and rate of combustion of compositions based on them has been studied. It is found that under normal conditions, a change in the mass content of nickel oxide from 75 to 30 % leads to a natural change in combustion modes: fire flame, a multi-stage mode, and a self-oscillating mode with periodic stripping of combustion products from the burning surface. It is shown that the maximum burning rate of such mixtures (82 mm/s) is achieved at an equal mass ratio of nickel oxide and titanium. In condensed combustion products of a mixture of nickel oxide with titanium, Ti₂Ni intermetallic and Ni₂Ti₄O _x double oxide identified.
