About Lanthanum oxide, 99.9%

Lanthanum oxide (CAS 1312-81-8) is a rare earth oxide offered by Vaqora Chemicals (AR grade), specified at 99.9% purity. Its molecular formula is La2O3 and its molecular weight is 325.81 g/mol. Its systematic (IUPAC) name is bis(lanthanum(3+)). Tris(oxygen(2-)). Common synonyms include Lanthanum(III) oxide and Lanthanum sesquioxide.

The material typically appears as a white powder. Key physical data: a density of 6.51 g/mL at 25 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for phosphors and glass, catalysts, magnets and ceramics and electronics and thin films. Buyers come mainly from academic and industrial research, electronics and semiconductors and metallurgy and mining.

We offer Lanthanum oxide in 100 g, 500 g, 5 kg and 4 x 25 kg packs with a batch-specific COA, and ship to customers worldwide.
