Data on the influence exerted by the synthesis conditions and by the nature and relative amounts of precursor reagents on the properties of metal-ammonium phosphates, promising as components of fire-retardant and fire-extinguishing additives, are summarized and analyzed. The manner in which the solution pH and nature and relative amounts of the reacting metal-, nitrogen-, and phosphorus-containing compounds affect the phase composition, solubility, aggregative state, and fundamental aspects of thermal transformations of products being synthesized on the basis of di- and trivalent metal-ammonium phosphates in a wide temperature range is determined.
