摘要

采用同步热分析（STA）、红外光谱（FTIR）和x射线粉末衍射分析等方法研究了次亚磷酸钙分散对大气氧氧化产物形貌和组成的影响。研究发现，次亚磷酸钙氧化过程中影响传热传质的因素是焦磷酸钙Ca2P2O7玻璃相的形成导致产物的非晶化。

Effect of Dispersion of Calcium Hypophosphite on the Macrokinetics of Its Oxidation

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.

期刊介绍： Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
