一般描述
La2O3是一种宽带隙p型半导体，也称为倍半氧化镧。它是唯一具有空Ln-4f外壳的镧系氧化物，广泛用于制备光学材料、电介质和导电陶瓷。La2O3也可用作许多有机转化的催化剂。
应用
LAMOX 快离子导体和超导体的前体。
氧化镧（III）提高了玻璃的耐碱性能，由于高折射率和低色散，被广泛应用于照相机和望远镜透镜、红外吸收玻璃和其他特种光纤的制备。例如，可作为起始材料制备用于诊断X射线屏蔽的La2O3-CaO-B2O3-SiO2玻璃。
可用于制备热膨胀系数高、导热系数低的热障涂料。
还可用作合成二苯基硫化物和硒化物的可循环催化体系。

Upon excitation in thin oxide films by infrared radiation, radiative polaritons are formed with complex angular frequency ω, according to the theory of Kliewer and Fuchs (1966 Phys. Rev. 150 573). We show that radiative polaritons leak radiation with frequency

The origin of dielectric anomalies and magnetodielectric response of La(2)MnCoO(6) has been investigated by means of ultra-high resolution synchrotron x-ray powder diffraction, neutron powder diffraction, resistivity, magnetization and dielectric measurements. The study has been performed on two different bulk samples
