摘要: 用回流、水热晶化和HF沉淀三种方法制备了α-Zr(HPO4)2·H2O(α-ZrP)晶体.HF沉淀法制备的α-ZrP晶体尺寸最大,层板有序度最高,水热法次之,回流法最差.水热法合成的α-ZrP尾板本身的结晶度最高.随α-ZrP晶粒增大,层板有序度和层间水的脱除温度均提高,并且需要嵌入更多的烷基胺和醇胺才能导致层板胶体化.HF沉淀法和回流法制备的α-ZrP层板较易水解,水热法制备的样品水解率较低,但三种样品在有机胺浓度为等当点时水解率均不超过20%.

Abstract: The crystalline a-Zr(HPO4)2·H2O(a-ZrP) was prepared by three different methods - reflux, hydrothermal crystallization and HFprecipitation.The a-ZrPsample obtained by the HFprecipitation is the largest in size and the highest in sheet orderliness, while the sample prepared by the reflux method is the smallest in size and the lowest in sheet order1iness.The highest unit-layer crystallinity of a-ZrPcrystal was obtained by hydrothermal method.With the crystal size and the sheet orderliness of the crystal increasing, the dehydration temperature rises, and more alkylamine or amino-alcohol is needed to intercalate into a-ZrPfor its colloidization.The samples from HFprecipitation and reflux methods are easier to hydrolyze than the sample from hydrothermal method, but the hydrolysis percentage of all samples from three different methods are lower than 20%, even if the concentration of amine reaches the equivalent point.
