kuparioksidi

Kuparioksidi, also known as copper(II) oxide or cupric oxide, is an inorganic compound with the chemical formula CuO. It is a black solid that is insoluble in water but soluble in acids. Kuparioksidi occurs naturally as the mineral tenorite.

This compound is primarily produced industrially by the aerial oxidation of copper metal at high temperatures or by heating copper(II) carbonate or copper(II) nitrate. Its physical properties include a relatively high melting point and a density of about 6.315 g/cm³.

Kuparioksidi has several important applications. It is widely used as a pigment in ceramics and glass, imparting a blue or green color. It also serves as a precursor for the production of other copper compounds, such as copper sulfate. In the field of catalysis, kuparioksidi is employed in various chemical reactions. Additionally, it finds use in the manufacturing of certain types of batteries and in electroplating processes. Its antimicrobial properties have also led to its exploration in some specialized applications.
