Superior nanopowder is the crucial of transparent ceramic.In order to prepare Nd∶GGG transparent ceramic,this article make use of sol-gel method to prepare the precursor powder of the transparent ceramic,and its goal is to obtain the homogenously dispersive and small size powder,and gain the high quality transparent ceramic.After obtained the powder of transparent ceramic,we have to character it,XRD spectra of the samples show that the samples exhibit the cube structure,the space group is Ia3d,its lattice constant is:A=123.7nm.The crystalline grain grows gradually with increasing temperature,and the powder reach the best state at 1000℃ for 8 hours;SEM shows the powder was sphere in shape and dispersed homogeneously.
