ceramic‑glass colouring

Copper oxide (cupric oxide, CuO) is a black fine inorganic oxide powder. It does not dissolve in water, but can dissolve in mineral acids to generate corresponding copper salts. This material serves as colorant for ceramics, enamel and glass glazes. It can act as catalyst or desulfurizer in chemical and petrochemical industries. Besides, it is the key starting material for producing many other copper‑based compounds, and also applied in analytical chemistry and new‑material preparation. We provide industrial‑grade and catalyst‑grade copper oxide.
