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。

特点和优势

  • 高折射率
  • 热稳定性
  • 硬度
  • 高介电常数
