Transcripción del resúmen realizada por el autor: Pyrotechnic mixtures can produce aerosol fire extinguishing agent by combustion and serve as an efficient and economic alternative to the halons. In this work, magnesium powder was used as an additive to improve the combustion performance of the strontium nitrate-based pyrotechnic aerosol fire extinguishing agent. Optimization was carried out regarding extinguishing time, residue mass, combustion temperature, corrosiveness, combustion product and mass burning rate. Even though magnesium powder is a high energy combustion agent, the results showed that the flame temperature could be controlled within a reasonable range of 700°C to 900°C by proper formulation, and the performance of the strontium nitrate-based aerosol fire extinguishing agent can be improved efficiently.
