| 摘 要： | 采用共沉淀法制备出性能良好的YAG(Y3A12(A1O4)3)纳米粉,对前驱体及不同温度下煅烧后的粉体进行差热、红外光谱、X射线衍射、比表面积和透射电镜等分析。结果表明:YAG粉体大小均匀,近似球形,且随着煅烧温度的升高,其颗粒逐渐变大,当温度达到1000℃时粉体全部为纯YAG立方相。随着母盐溶液(Y(NO3)3+Al(NO3)3)浓度的降低颗粒逐渐减少,并且粉体中YAM(Y4A12O9),Y2O3等相转化为纯YAG立方相。

| Abstract: | YAG nano-size powders were prepared by co-precipitation method, the precursor and powders after being calcined under different temperature were characterized by TG/DTA, IR, XRD, BET and TEM. The results show that YAG nano-size powders assumes spherically and distribute equably, and with the increase of calcination temperature, the grain increases gradually, the pure YAG cubic phase crystallite can be obtained at 1 000℃. With the decrease of mother solution concentration, the grain reduces gradually, and the YAM, Y_2O_3 phases of the powders change to pure YAG cubic phase. |
