Abstract
The setting reactions and thermal degradation of the phosphate binders are interpreted from the DTA and X-ray diffraction data. Setting takes place through complex formation of (NH4Mg PO4.6H2O)n, excess reactants, and water. Dehydration and thermal reactions lead to a sequence of reactions forming (NH4MgPO4.H2O)n, (Mg2P2O7)n, Mg2P2O7, and Mg3(PO4)2.
摘要
根据差示热分析（DTA）和X射线衍射数据对磷酸盐粘结剂的凝结反应和热降解进行了解释。凝结过程是通过形成(NH4Mg PO4.6H2O)n、过量反应物和水的络合物来发生的。脱水和热反应导致一系列反应，形成(NH4MgPO4.H2O)n、(Mg2P2O7)n、Mg2P2O7和Mg3(PO4)2 。
