POWDER CHARGE FOR LIGHT-GAS GUN Russian patent published in 2013 - IPC C06B27/00 C06D5/00 C10L3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to rifles and specifically to a powder charge for a light-gas gun or firearm. The powder charge contains gaseous borane and phosphine or a solution of liquid borane and phosphine and is meant to be put under pressure in a cartridge chamber or bore in form of a metal or composite cylinder, actuation of which is triggered by a heat source lying in the breech end or the front end of the bore, inside or outside it. Use of catalysts in form of carbon, soot, graphite or methane is also possible, as well as retarders such as hydrides, having a negative enthalpy of formation, i.e. an endothermic decomposition reaction, e.g. hydrides of beryllium, lithium, aluminium, calcium or a mixture thereof. The heat source if a capsule, an electric coil, a spark or an explosive or cumulative charge, lying inside or outside the bore.

EFFECT: invention provides high muzzle velocity, simplifies the design of the gun, increases firing speed, reduces the weight of the gun and cost of firing.
