paths, dependent on the combination of phases present and the experimental variables, especially the atmosphere. By heating samples to various temperatures, quenching to room temperature and examining the reaction products by X-ray diffraction, the phases formed after various heat treatments have been identified. The most important reaction sequence on heating in the presence of excess MgO is
摘要 NH4MgPO4·H2O、NH4MgPO4·H2O 和 (NH4)2Mg(HPO4)2·4H2O 的 DTA 和 TG 曲线是复杂的,因为有几个重叠反应和不同的反应路径,取决于存在的相组合和实验变量,尤其是气氛。通过将样品加热到各种温度,淬火到室温并通过 X 射线衍射检查反应产物,已经确定了各种热处理后形成的相。在过量 MgO 存在下加热最重要的反应顺序是
