gas-generating formulas. SUBSTANCE: invention relates to formulas of gas-generating composites used for displacing liquid and powder-like substances, pressure making and so on. The composition comprises the following components, wt.%: potassium nitrate, 50.0-60.0; novolacs phenol-formaldehyde resin, 19.0-24.0; magnesium basic carbonate, 7.0-15.0; ammophos, 2.0-8.0; potassium chloride, 3.0-12.0. The composition shows the improved exploitation indices due to decrease of temperature of gases formed and enhanced specific gas-output index. EFFECT: improved properties of composite. 1 tbl
