以Al粉、盐酸和Dy（CH 3COO）3. 4 H2O为原料，采用水溶胶-凝胶法合成了镝铝石榴石（DAG）纳米粉体。将干燥的无定形凝胶在800- 1，200 °C的范围内热处理。采用X射线衍射、扫描电镜、热重-差热分析和傅里叶变换红外光谱等方法研究了热处理对干凝胶结晶和相变的影响。结果表明，从900至1，200 ℃煅烧的凝胶导致形成具有26至98 nm粒度分布的结晶DAG纳米粉末。
A dysprosium aluminum garnet (DAG) nanopowder was synthesized by aqueous sol–gel method using Al powder, HCl and Dy(CH3COO)3·4H2O as raw materials. The dried amorphous gel was heat treated in the range of 800–1,200 °C. The influence of heat treatment on crystallization and phase transformation of the dried gel was investigated using X-ray diffractometery, scanning electron microscopy, thermogravimetry and differential thermal analysis and Fourier transform infrared spectroscopy. It was shown that the gel calcined from 900 to 1,200 °C resulted in the formation of a crystalline DAG nanopowder with particle size distribution ranges from 26 to 98 nm.
