The experimental data is presented in the article concerning the impact sensitivity of mixtures of ocfol-3,5 (octogen) with various metal oxides (Fe₂O₃, V₂O₅, TiO₂, particle size is 1–2 µm). The experiment was carried out by the method of critical pressures using a tensometric technique. As a result obtained are the dependences of the critical pressure of octogen mixtures initiation with metal oxides on the mass content of the latter. For the mixture of octogen + Fe₂O₃, significant sensitization of the base explosive was noted at an additive concentration of 30 %. With an increase of the iron oxide content in the mixture, a gradual decrease in its impact sensitivity is observed. When considering a mixture of octogen + V₂O₅, the similarity of the process with that observed when using iron (III) oxide in a mixture was shown, however, the quantitative indicators still differ slightly. With an increase in the concentration of V₂O₅ to 50 %, a sharp jump in the critical pressure of initiation is noticeable, which was not observed when the iron oxide was involved. Starting already from this fraction, the additive does not have a sensitizing effect on the base explosive.

When considering the mixture of octogen + TiO₂, its qualitative difference from the other two mixtures was noticed. In the area of low concentrations, the effect of dioxide on the sensitivity of the explosive is almost imperceptible. With a further increase in the mass fraction of titanium oxide in the mixture, a sharp sensitization is observed, in which the clear minimum was not found, and the concentration, at which a decrease in the sensitivity of the mixture would be observed, was not determined either. Minimum critical pressure for initiating an explosive reaction for Fe₂O₃ and V₂O₅ is in the range of mass fractions of 10–15 %, and is equal to 0.46 and 0.52 GPa, respectively. For mixtures of octogen + TiO₂, this minimum is expressed dimly, and is equal to 0.55 GPa.
