摘　　要：氧化镥因其优秀的物理化学性质,被认为是极具应用潜力的闪烁透明陶瓷基质材料。目前国外已经对Eu^(3+)∶Lu_(2)O_(3)闪烁透明陶瓷有了系统研究,能够制备大尺寸样品,对于Gd^(3+)改良Eu^(3+)∶Lu_(2)O_(3)性能的研究也比较深入,同时还开发了Nd^(3+)∶Lu_(2)O_(3)闪烁透明陶瓷的应用潜力。国内在此领域仍处于落后阶段,尚未制备出大尺寸样品。为了有所突破,对粉体制备工艺继续进行探究,以期制备出高纯度、粒径小且分布均匀、粉体团聚集程度较低的粉体,同时要在成形和烧结工艺上有所突破,实现高性能闪烁透明陶瓷的制备。Lutetium oxide is considered a promising flashing transparent ceramic matrix material due to its excellent physicochemical properties.At present, other countries have had a systematic research on Eu^(3+)∶Lu_(2)O_(3) scintillator transparent ceramics, which can prepare large-size samples. The performance of Gd^(3+) modified Eu^(3+)∶Lu_(2)O_(3) is also well studied. The application potential of Nd^(3+)∶Lu_(2)O_(3) scintillator transparent ceramics is also developed. Domestic in this field is still in the backward stage, has not yet prepared large-size samples. The powder preparation process needs to be explored further, in order to prepare the powder with high purity, small particle size, uniform distribution and low degree of powder mass aggregation. At the same time, breakthroughs should be made in the molding and sintering process to achieve the preparation of high-performance flashing transparent ceramics.
