Abstract
The influence of chemical impurities on hygroscopic properties, as well as on the grinding and modification efficiency of ammonium phosphate and ammonium sulfate was analyzed. It was shown that application of chemically pure ammonium sulfate and ammonium phosphate free of ammonium fluoride and magnesium phosphate impurities provides the best conditions for obtaining fire extinguishing dry powders with high fire suppression ability and properties that satisfy relevant specifications.
