摘　　要：钇铝石榴石(YAG)具有稳定的化学性能,在作为化工新型材料使用中得到了广泛应用。本文通过利用共沉淀法制备超细YAG粉体。通过研究可以得到,前驱体在1100℃下煅烧1h后,生成了纯的YAG晶体。合成的YAG颗粒比较分散、细小,其粒度大小相当均一,粉体颗粒粒径在200～350nm之间,其颗粒近似球形,颗粒之间有部分烧结现象出现。YAG is widely applied as a new chemical material because of some excellent performances in the chemistry. The pure superfine YAG powders are prepared via the co-precipitation method after calcining the precursor of YAG at 1100℃. The superfine YAG powders have better dispersion and narrow particle size distribution range between 200 and 350nm. The superfine YAG particles are mainly near-spherical, and some are partly sintered.
