Tm2O3

Notas

Thulium(III) oxide (Tm2O3) is a crystalline material characterized by its pale green coloration. Historically identified in 1879 by Swedish chemist Per Teodor Cleve as a component derived from impure erbia, the compound serves as a rare earth oxide within ceramic systems. In the context of glaze chemistry, thulium oxide functions primarily as a specialty additive; like other rare earth oxides, it can act as a refractive agent, potentially modifying the optical properties and light interaction of a glassy matrix. Its influence on glaze viscosity, thermal expansion, and melting behavior remains specialized, often used in research or advanced aesthetic applications where unique color responses or glass structural modifications are required.
