中文摘要：

综述了目前常用的制备镁铝尖晶石粉体的各种方法的工艺过程、特点及其产物的性能特征。经分析指出纯度和粒度是粉体最重要的两个性能指标；降低合成温度、简化工艺过程是今后制备技术发展的趋势。金属醇盐可能成为获得高纯度产物最有应用前景的前驱物；水热处理、溶剂蒸发、超临界干燥等物理手段是解决粒度最有效的途径。

英文摘要：

A brief reviewed on the processes and characteristics of various techniques preparing magnesium aluminate spinel powders, and their product properties. Its purity and particle size distribution is the two most important indexes of MgAI2O4 Spinel Powders. Preparation technologies are about to lower synthesis temperature and simplify process. Metal alkoxides may be the most potential precursors. Hydrothermal method, evaporation technique, supercritical drying etc. may be the most effective routes.
