Influence of the Gas Medium Composition on the Thermal Decomposition of Ammonium, Sodium, Potassium, and Calcium Hypophosphites
摘要
Abstract
The key step of the thermal decomposition of hypophosphites is disproportionation determining the phase composition and morphology of the final products. The distinctive features of the thermal decomposition of hypophosphites are the formation of polyphosphoric acid from ammonium hypophosphite and of red phosphorus from the metal hypophosphites. The thermal decomposition of hypophosphites in air is accompanied by large heat release.
