FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry and can be used for producing fire-extinguishing mixtures to fight fires of class A, B, C and electric installations. As an additive to fire suppressant powders on bicarbonate or ammonium-phosphate basis used is a synthetic mineral alloy powder with the particle size of 40-100 mcm. Additive of the synthetic mineral alloy powder provides the fire suppressant composition with uniform properties and higher efficiency of extinguishing electric equipment under load owing to increasing the period of maintaining dielectric properties of the additive.
EFFECT: provided is expansion of raw material resources additives to fire suppressant powders.
