Synthesis and analysis of new non-corrosive hot aerosol fire suppression agent

A synthesized new S-type aerosol forming agent composed of strontium nitrate and magnesium powders majorly is developed to replace currently dominate corrosive K-type aerosol forming agent which is based on potassium nitrate on the market. In fire extinguishing test, new S-type aerosol forming age...
