Abstract

Thermodynamics of boehmite formation upon hydrothermal treatment of micron-size particles of hydrargillite and γ-Al₂O₃ at 200°C in various media has been studied at various treatment times. The presence of surface-bound water with low evaporation enthalpy value at the initial stages of precursor hydrothermal treatment has been revealed. It has been shown that, irrespective of precursor and hydrothermal treatment medium, the prepared boehmite has similar properties

水铁矿和γ-Al2 O 3的水热处理产物中的水态

摘要

在水铝矿和γ-Al系的微米尺寸的粒子的水热处理勃姆石形成的热力学₂ ö ₃在各种介质中在200℃下进行了研究，在不同的处理时间。已经发现在前体水热处理的初始阶段存在具有低蒸发焓值的表面结合水。结果表明，无论前驱体和水热处理介质如何，所制备的勃姆石均具有相似的性能。
