Description
- General description: La2O3 is a wide band gap p-type semiconductor also called lanthanum sesquioxide. It is the only lanthanide oxide with an empty Ln-4f shell and is widely used to prepare optical materials, dielectrics, and conductive ceramics. La2O3 can also be used as a catalyst in many organic transformations.
- Application: Lanthanum(III) oxide improves the alkali resistance of the glass and because of its high refractive index and low dispersion, it is widely used in the preparation of camera and telescope lenses, infrared-absorbing glasses, and other special optical fibers. For example, it can be used as a starting material to prepare La2O3-CaO-B2O3-SiO2 glass for diagnosis X-ray shielding.It can be used to prepare thermal-barrier coatings with a high thermal expansion coefficient and low thermal conductivity.It can also be used as a recyclable catalytic system for the synthesis of diphenyl sulfides and selenides.
- Features and Benefits: High refractive indexThermal stabilityHardnessHigh dielectric constant
