The Nd∶YAG powder was prepared using co-precipitation method by the addition of different dispersants and characterized by laser particle analyzer,SEM and XRD.The result showed that the powders with 5% of PEG(4000) as the dispersant were dispersed after being calcined at 1100°C for 2 hour.The precursor completely transformed into YAG phase without other crystalline phase.The size of individual grain was less than 100 nm.
