Effect of Dispersion of Calcium Hypophosphite on the Macrokinetics of Its Oxidation
摘要
Abstract
The effect of calcium hypophosphite dispersion on the morphology and composition of the products of its oxidation by atmospheric oxygen has been studied by simultaneous thermal analysis (STA), FTIR spectroscopy, and X-ray powder diffraction analysis. It has been found that the factor influencing the heat and mass transfer in the oxidation processes of calcium hypophosphite is the amorphization of the products due to the formation of the glass phase of calcium pyrophosphate Ca2P2O7.
