SYNTHESIZING YTTRIUM ALUMINUM GARNET (YAG) NANO-POWDER BY LOW TEMPERATURE COMBUSTION

摘要：

Transparent polycrystalline Y3Al5O12 (YAG) ceramic with better chemical stability, excellent optical and high temperature mechanical properties is a new laser host material that appears a competitive substitute for the YAG single crystal. YAG transparent ceramic with excellent properties can be obtained by using synthesized nano-powder. Precursor of yttrium aluminum garnet (YAG) was synthesized by Low temperature combustion method withY2O3、Al(NO3)3·9H2O、citric acid and Ethylene Glycol as raw material. The precursor precipitant is characterized by IR, TG/DSC, XRD, and SEM. The precursor is calcined at different temperatures. It is found that the precursor completely transforms to YAG phase at about 900℃. YAG powers with nanometer size, homogeneous dispersion, hard-agglomeration-free can be obtained by this method.
