RuO2

Notas

Ruthenium(IV) oxide, represented by the chemical formula RuO2, is a stable black solid characterized by a rutile crystal lattice structure. Within the scope of ceramic chemistry, it is recognized primarily for its role as a specialized inorganic compound rather than a traditional glaze-forming ingredient. While it functions extensively in industrial electrochemical applications—such as serving as an electrocatalyst for the production of oxygen, chlorine, and various chlorine oxides—its specific behavior regarding traditional glaze fluxing, viscosity modification, or thermal expansion properties in ceramic systems is not documented in standard oxide literature. Consequently, RuO2 is not typically categorized as a glass former or common pigmentary agent in standard ceramic glaze development.
