Basic copper carbonate is a double salt combining copper carbonate and hydroxide, forming vibrant green crystalline solids. Unlike simple carbonates, it decomposes endothermically around 200°C, yielding copper(II) oxide, water, and carbon dioxide—key for controlled ceramic glaze coloration.
Basic Cupric Carbonate, synonymous with natural malachite, forms as a striking green mineral through copper ore weathering or aqueous precipitation. Historically prized as "mountain green" pigment in Renaissance art, it also develops as a protective patina on copper roofs and statues.
Copper carbonate basic at 99% purity is synthesized via controlled precipitation or hydrothermal methods, ensuring minimal metallic impurities (Fe, Ni, Sb <0.1%). This ultra-pure grade exhibits consistent particle size distribution and crystallinity, validated by XRD and ICP-MS.
Copper carbonate basic powder, commonly known as malachite when natural, is a vibrant green, fine-grained solid. Synthesized via precipitation of copper salts with carbonates, it exhibits low water solubility but reacts vigorously with acids, releasing CO₂. This compound decomposes at ~200°C to copper oxide, CO₂, and water.
High purity copper carbonate basic, often called natural malachite, is a fine green powder exceeding 99% purity. Unlike simple carbonates, it features a basic structure with hydroxide groups. This high-grade material decomposes controllably around 200°C, yielding copper oxide and CO₂ without impurities.
