Product Overview
Cuprous Oxide, chemically known as Copper(I) Oxide, is a vital inorganic compound widely utilized across multiple industrial sectors. Represented by the molecular formula Cu2O, this substance appears as a distinctive red powder with high stability under dry conditions. Our manufacturing process ensures exceptional purity levels, making it an ideal choice for demanding applications such as ceramic colorants, glass staining agents, and marine antifouling coatings. As a leading global manufacturer, we provide consistent quality backed by comprehensive Certificates of Analysis (COA).
Chemical Properties
This compound exhibits specific physical and chemical characteristics that define its utility in specialized chemical processes. With a molecular weight of 143.09 g/mol, Cuprous Oxide possesses a specific gravity of approximately 6.00. It features a high melting point of 1235 degrees Celsius and a boiling point around 1800 degrees Celsius. While stable in dry air, it is susceptible to slow oxidation into cupric oxide when exposed to humid environments. The material is insoluble in water and alcohols but dissolves readily in acids, ammonia water, and ammonium chloride solutions. Users must note that the substance is toxic and requires careful handling according to safety protocols.
Industrial Applications
The versatility of Cuprous Oxide makes it a cornerstone material in several key industries. In the marine sector, it serves as a primary active ingredient in ship bottom anti-fouling paints, preventing biological accumulation on hulls. In the ceramics and glass industries, it functions as an effective colorant and staining agent, imparting specific red hues to finished products. Additionally, it is employed as a bactericide in various formulations and serves as a critical analytical reagent in laboratory settings. Our technical grade and agricultural grade options cater to diverse performance requirements across these fields.
