Abstract

A new approach to prepare highly dispersed calcium aluminate at temperatures from 900°C with desired properties (bulk density starting from 0.015 g/cm³, particle size falling in the range of 7–42 nm) is described, which consists of step-by-step heat treatment of a concentrated aqueous solution of Al(NO₃)₃, Ca(NO₃)₂, and C₆H₈O₇ in the molar ratio CaO : Al₂O₃ = 1 : 2. The main stages of the synthesis are studied by X-ray powder diffraction, IR spectroscopy, as well as scanning and transmission electron microscopies. The highly dispersed calcium aluminate obtained using the developed approach has pronounced luminescent properties.

低温合成高度分散的铝酸钙

摘要介绍了一种在 900°C 以下温度条件下制备具有所需特性（体积密度从 0.015 g/cm3 开始，粒度在 7-42 nm 范围内）的高分散铝酸钙的新方法，包括逐步热处理 CaO : Al2O3 = 1 : 2 的 Al(NO3)3、Ca(NO3)2 和 C6H8O7 的浓水溶液。通过 X 射线粉末衍射、红外光谱以及扫描和透射电子显微镜对合成的主要阶段进行了研究。利用所开发的方法获得的高分散铝酸钙具有明显的发光特性。
