| 英文摘要 | Highly sinterable yttrium aluminum garnet (yag) nano-powders have been synthesized by a sol-gel combustion method with various chelating agents and fuels, namely citric acid, tartaric acid, glycine and ethylene diamine tetraacetic acid (edta). the preparation involved the thermal decomposition of a chelating agent (fuel)-nitrate gel and the formation of amorphous precursors. the as-synthesized precursors were studied by infrared spectroscopy (ir), thermogravimetric (tg) and differential scanning calorimetric (dsc) analyses. the nano-powders calcined at 1000 degrees c were characterized by x-ray powder diffraction (xrd) and transmission electron microscopy (tem). it was found that the chelating agents and fuels used had a significant influence on the average grain size and agglomeration of yag nano-powders. the rate of combustion reaction between chelating agent (fuel) and nitrate was responsible for the growth of the grains. nano-particles with the smallest size and high sinterability were obtained when using edta, which derived from the significant blocking of the diffusion path associated with the lowest combustion reaction rate.
