La2O3

Notas

Lanthanum(III) oxide (La2O3), referred to as lanthana, is a rare-earth oxide utilized in specialized ceramic and material science applications. While not a primary glass-forming oxide, its incorporation into high-performance glass compositions is valued for its contribution to optical properties, particularly in producing glasses with high refractive indices and low dispersion. Beyond its optical utility, the oxide serves as a constituent in specific ferroelectric ceramics and functions as a precursor in the development of catalytic materials. In ceramic glaze chemistry, lanthanum is characterized as a heavy, refractory oxide that can modify melt viscosity and influence surface durability, often providing structural stability in complex glaze formulations.
