Tb2O3

Notas

Terbium(III) oxide (Tb2O3), classified as a rare earth sesquioxide, functions primarily as a specialty additive in ceramic systems. Chemically, it exists as a p-type semiconductor characterized by proton-conducting properties, which can be further modified through calcium doping. In its standard preparation, the material is obtained via the high-temperature reduction of terbium heptoxide (Tb4O7) in a hydrogen atmosphere. While its technical profile is defined by these specific electronic and chemical characteristics, its application in glazes is typically associated with its role as a stable rare earth component, often utilized for its unique optical contributions and potential to influence glass structure stability.
