The time-delay compounds serve to create the necessary time delays that ensure a given duration of work. These compounds consist of low-level oxidants and combustible, so their energy and combustion temperature are relatively low. Today an increased interest in slowly burning mixtures with delay composition is noticed. It is associated with an obvious tendency towards miniaturization of the slowing elements of various devices. The article describes development of a delay composition based on chromium barium and titanium diboride burning slowly at a burning rate of 1.26 mm/s. For researching the combustion process, the samples were burned in a bomb with a constant pressure in an argon medium. Regularities of burning of the mixture BaCrO4/TiB2 in the medium of inert gas have been investigated. At combustion of the slow-burning BaCrO4/TiB2 spinel-shaped crystalline structures are formed. The prepared slow-burning composition, not sensitive to mechanical influences and possessing high physico-chemical stability, can be used in the pressure-sealed delay devices.
