Burning of mixtures of copper oxide with titanium

This paper describes the study of the effect of physical and chemical properties of powder titanium and ratio of the original components on the burning parameters of its mixtures with copper oxide. It is shown that the linear burning rate of such mixtures is significantly dependent on the brand of used titanium. Under normal conditions, the mixtures can stably burn with the content of copper oxide of not smaller than 13%. With an increase in the content of copper oxide to a stoichiometric ratio, there is a change of burning regimes: multifocal, multifocal with detachment of solid residue, combination of convective and multifocal, multifocal with melt formation, fiery torch, and fireball. It is determined that, in this system, there may be convective burning under atmospheric pressure in the absence of outer reinforcement.
