Cuprous oxide red extra pure

Cuprous oxide red extra pure, also known as copper(I) oxide (Cu2O), is a red crystalline powder with a cubic crystal structure. Its red color intensity depends on particle size, ranging from yellow to dark red. It has a melting point of approximately 1232°C and a density of about 6.04 g/cm³. Cuprous oxide is practically insoluble in water but soluble in ammonia and reacts with hydrochloric acid to produce cuprous chloride.​

This compound occurs naturally as the mineral cuprite and is widely used as a pigment in red glass, ceramics, and antifouling marine paints. It also serves as an agricultural fungicide, organic synthesis catalyst, and material for electroplating and semiconductor applications. The extra pure grade indicates high purity with minimal impurities, making it suitable for industrial and research applications requiring precise and stable material
