Copper powder is a reddish-brown metallic powder with a characteristic metallic luster. It is a fine, free-flowing material commonly used in metallurgy, electronics, and chemical applications due to its high thermal and electrical conductivity.

🏭⚗️ Production
Copper powder is typically produced by methods such as electrolytic deposition, atomization of molten copper, or chemical reduction of copper salts (such as copper sulfate or copper nitrate) using reducing agents like hydrogen or ascorbic acid. The method of production affects the particle size, purity, and morphology of the final product.

🔬 Properties
Copper powder has the chemical formula Cu and a molar mass of 63.55 g/mol. It appears as a reddish-brown metallic powder and is insoluble in water but reacts slowly with moist air, forming a green patina of copper carbonate over time. It has excellent electrical and thermal conductivity, with a melting point of about 1085 °C and a density of approximately 8.96 g/cm³. Depending on its grade and form, it may exhibit irregular, spherical, or dendritic particle shapes.

🧪 Applications
Copper powder is widely used in powder metallurgy for manufacturing self-lubricating bearings, electrical contacts, and sintered components. It is also used in conductive inks and pastes for electronics, in welding and brazing, and as a catalyst in chemical reactions. In laboratories and research, it serves as a reagent and a material for nanotechnology development.

⚠️ Safety
While copper powder is not highly toxic, inhalation of fine dust may cause respiratory irritation or a condition known as metal fume fever if the material is heated. Prolonged skin contact may cause irritation in sensitive individuals. It should be handled in a well-ventilated area, using proper dust control measures and personal protective equipment such as gloves and masks. The powder is combustible in fine form and may pose a fire or explosion hazard when dispersed in air in sufficient concentrations. It should be stored in a cool, dry place away from strong oxidizers.
