Lanthanum Oxide Uses: Glass Use Lanthanum Oxide.

Dilanthanum Trioxide is a critical rare earth material. Rare earth La2O3 is active in glass, ceramics, electronics, and other fields.

Lanthanum Oxide Is much in precision glass production, like precision optical glass and optical fiber.

Making optical glass use La2O3 can increase the refractive index, reduce dispersion, and improve the chemical corrosion resistance of the glass. The content of La2O3 in the glass is 10%~40%, sometimes more than 60%.

Lanthanum optical glass is borate or borosilicate optical glass with Lanthanum Sesquioxide as the main component. Dilanthanum Trioxide has optical characteristics of high refraction and low dispersion. Lanthanum Oxide can improve its chemical stability and life, increasing its hardness and softening temperature.

In addition, during the glass manufacturing process, when the glass is heated to a high-temperature state, a thin film is formed on the surface of the glass. The film will gradually decompose if the heating temperature is too high or the time is too long. So causing the glass to burst. Making Glass use of Lanthanum Trioxide can form a stable oxide protective film on the surface. This prevents the glass surface from decomposing and slows the build-up of thermal stress. And reduces the risk of glass bursting. In addition, Dilanthanum Trioxide can also enhance the heat resistance, wear resistance, and corrosion resistance of glass. And it also improves the quality and reliability of glass.
