Frequently Asked Questions

What is basic copper carbonate?

Basic copper carbonate is copper(II) carbonate hydroxide, CAS 12069-69-1, the synthetic equivalent of the mineral malachite. Industry references record use as a pigment, in pyrotechnics, as an algaecide and seed-treatment fungicide, in bronze plating, and as a copper source in animal feed. It is supplied as a green powder.

What is the difference between copper carbonate and basic copper carbonate?

Simple copper carbonate (CuCO3) is unstable and rarely isolated; the commercially available 'copper carbonate' is in fact basic copper carbonate, copper(II) carbonate hydroxide [CuCO3·Cu(OH)2]. The basic form is the stable green compound sold in commerce.

What is CuCO3·Cu(OH)2 called?

That formula is basic copper carbonate, also known as copper(II) carbonate hydroxide and, in its natural mineral form, malachite. CAS 12069-69-1.

What are the main industrial uses of basic copper carbonate?

Per uses, it serves as a green pigment for paints and ceramics, a copper source in animal feed, a seed-treatment fungicide and algaecide active, a copper source for bronzing and plating baths, and a copper colorant in pyrotechnics.

How is bulk basic copper carbonate packaged?

It is supplied as a green powder in bags and drums. Request a CoA and SDS with your quote to confirm copper content, particle size, and grade for pigment, feed, or plating use.
