1.Product Introduction
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. This compound bridges geology and human industry, occurring in oxidized copper zones while serving as a key corrosion product. Its stable, vibrant hue and natural abundance made it significant in ancient metallurgy, decorative arts, and early chemical studies, embodying the intersection of mineralogy and material culture across civilizations.

3.Product Feature And Application
Basic Cupric Carbonate is integral to wood preservation formulations, providing controlled copper release to inhibit fungal decay and insect infestation in timber. It functions as a precursor for synthesizing copper naphthenate, a key preservative for textiles and marine materials. In organic synthesis, it serves as a mild oxidizing agent and catalyst for coupling reactions, enabling efficient pharmaceutical intermediate production. The compound also acts as a micronutrient supplement in specialty fertilizers for copper-deficient crops, enhancing chlorophyll synthesis. Its low solubility ensures sustained action in protective coatings and industrial biocides, offering environmental stability and reduced leaching risks.
4.Product Details
Basic Cupric Carbonate forms monoclinic prismatic crystals with a Mohs hardness of 3.5–4.0. It is diamagnetic and insoluble in water but dissolves in ammonia, forming deep blue complexes. Releases CO₂ upon acid contact. Dust poses respiratory risks; use NIOSH-approved masks. Stable below 200°C in dry air.
5.Product Qualification
We have received numerous government awards in China for our outstanding products and integrity in business operations. For exports, we hold REACH certification for multiple products, meeting EU import requirements for copper salt products. We are certified under the ISO 9001 Quality Management System and comply with RoHS standards. We can provide Safety Data Sheets (SDS) and all necessary documentation for every product.
6.Deliver,Shipping And Serving
In terms of packaging, we currently have two packaging options: bags and drums, their standard is 25kg. each pallet can load a total of 1 ton of goods. Some of the products will be in the ordinary bag on the basis of increasing the ton bag for uniform packaging, in the protection of the product at the same time to ensure the beauty of the goods. For some special products or special needs of customers, we can ensure the sealing and safety of the products by the form of barrel.
7.FAQ
What are the delivery terms available?
Generally, we commonly use FOB and CIF for delivery. If the customer has other delivery requirements, we can also discuss and negotiate.
