摘要

我们研究了焦磷酸锌(Zn2P2O7) α-相在25℃时的水蒸气吸收率。该化合物被发现具有高度的吸湿性，因为它形成了一种晶体水合物，组成为Zn2P2O7∙5H2O。它的结晶水的去除有三个步骤，从60°C开始，到400°C完成。脱水产物的相组成取决于热处理温度。在500℃以下，我们观察到γ-Zn2P2O7的大量非晶化和主要形成，而在600℃以上退火可以得到相纯的α-Zn2P2O7。

A Study of α-Zn2P2O7 Hygroscopicity

We have studied water vapor absorption by the α-phase of zinc pyrophosphate, Zn₂P₂O₇, at 25°C. This compound has been found to be highly hygroscopic owing to the formation of a crystalline hydrate with the composition Zn₂P₂O₇∙5H₂O. Removal of its water of crystallization has been shown to occur in three steps, starting at 60°C and reaching completion at 400°C. The phase composition of the dehydration product depends on heat treatment temperature. Below 500°C, we observe considerable amorphization and predominant formation of γ-Zn₂P₂O₇, whereas phase-pure α-Zn₂P₂O₇ can be obtained as a result of annealing at temperatures above 600°C.
