摘要：

A dysprosium aluminum garnet (DAG) nanopowder was synthesized by aqueous sol-gel method using Al powder, HCl and Dy(CH3COO)(3)center dot 4H(2)O as raw materials. The dried amorphous gel was heat treated in the range of 800-1,200 A degrees 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 A degrees C resulted in the formation of a crystalline DAG nanopowder with particle size distribution ranges from 26 to 98 nm.
