The invention relates to explosives mixed type.

Known for CENTURIES, see, e.g., us Pat. No. 2486436, 2486437 "Charge Staroverova - 7 and 10, consisting of an explosive mixture of substances.

The task and the technical result of the invention - increase the pressure at the shock wave front by separating mainly hydrogen, and by rational joint use of the two energy reactions is the oxidation of carbon, boron, or metals, and the formation of boron nitride And regulation of the reaction rate.

The speed of sound in hydrogen even at normal temperature and a pressure of 1330 m/s. and if we slightly increase the temperature of hydrogen, the speed of sound in it and the shock wave velocity will increase dramatically. For example, hydrogen with a temperature of 650°C (this temperature below its ignition) will have a speed of sound of 2360 m/s.

Based on this and the idea of this invention. For this reaction should give pure hydrogen and solids. A suitable chemical reaction for this may be ternary (three component) deenergizes (there are two energy reactions: oxygen-metal and nitrogen-boron) reaction of lithium or aluminum and their compounds involving boron.

The most heat will have reactions involving beryllium, for example
