kupariIIoksidi

KupariIIoksidi, also known as copper(II) oxide, is an inorganic chemical compound with the formula CuO. It is a black solid that is insoluble in water but soluble in dilute acids. KupariIIoksidi is a p-type semiconductor and is used in various applications, including pigments, catalysts, and in the production of other copper compounds.

Historically, kupariIIoksidi has been used as a pigment in ceramics and glass, imparting a blue or green color depending on the firing conditions. It is also employed as a catalyst in many chemical reactions, such as the oxidation of carbon monoxide. In agriculture, it can be used as a fungicide or algaecide. Furthermore, kupariIIoksidi is a precursor for the synthesis of other copper salts and oxides, which have their own diverse industrial uses.

The production of kupariIIoksidi typically involves the heating of copper metal in air or oxygen at elevated temperatures. Alternatively, it can be formed by the thermal decomposition of copper(II) carbonate or copper(II) nitrate. Its semiconductor properties are of interest in research for applications in electronics and solar energy. Environmental considerations regarding copper compounds often focus on their potential toxicity to aquatic life, necessitating responsible handling and disposal.
