Lanthanum oxide (La2O3) is representative of high-purity rare-earth functional oxides. It is extensively applied in optical glass (high-refractive-index glass, infrared-absorbing glass), catalyst supports, special ceramics and electronic-ceramic materials. Key purchasing considerations for lanthanum oxide: total rare-earth oxides (TREO), loss-on-ignition, particle-size distribution, specific-surface-area and critical-impurity levels (Ce, Nd, Fe, Si, Ca etc.). Requirements for particle-size and impurities vary sharply across end-uses: optical-glass manufacturing is highly sensitive to colour-forming impurities such as iron and chromium, whereas catalyst-support applications prioritise specific-surface-area and pore-size distribution. Diversified product grades are available with precise particle-size control. Flexible deliveries span kilogram-scale R&D samples through ton-level bulk quantities, enabling seamless transition between customer R&D and mass-production phases.
