CuCO3

Copper carbonate (CuCO3) is an inorganic ceramic compound featuring copper bonded with a carbonate group, commonly occurring as a natural mineral (malachite, azurite) or synthesized for industrial use. It serves primarily as a pigment, catalyst precursor, and chemical intermediate in copper metallurgy, fungicide production, and decorative coatings, valued for its distinctive green color and reactivity. Engineers select it where copper-based catalysts, antimicrobial surfaces, or specific pigmentation are needed, though its thermal instability (decomposes at moderate temperatures to release CO₂) limits high-temperature structural applications compared to alternative ceramic oxides.
