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.
1.Product Introduction
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. Its low solubility and thermal stability make it ideal for synthesizing high-purity copper catalysts, advanced ceramic pigments, and specialized electronic materials. Precise stoichiometry ensures consistent performance in applications like wood preservatives and as a precursor for superconducting thin films, where trace metal contaminants are detrimental.

3.Product Feature And Application
High purity copper carbonate basic serves as a critical precursor in pharmaceutical synthesis, enabling precise copper-doped drug formulations with enhanced bioavailability. It functions as a precision electrode material in alkaline batteries, improving ion conductivity and cycle stability. The compound’s controlled reactivity allows its use in specialized anti-fouling marine coatings, where it gradually releases biocidal copper ions to inhibit microbial growth on ship hulls. Additionally, it acts as a high-purity copper source for synthesizing quantum dot sensitizers in next-generation photovoltaic cells, boosting light absorption efficiency. Its low impurity profile ensures consistent performance in these advanced applications.
4.Product Details
High purity copper carbonate basic appears as an intense green crystalline powder. It is insoluble in water but dissolves in acids with effervescence. Requires storage under inert atmosphere to prevent moisture absorption and CO2loss. Molar mass: 221.1 g/cm³. Exhibits weak antiferromagnetic ordering below 10K.
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
