Basic nickel carbonate

Basic nickel carbonate (CAS 12607-70-4, EC 235-715-9) is an inorganic nickel salt also known as nickel carbonate hydroxide, basic nickel(II) carbonate, and nickel carbonate reagent. It carries no assigned E-code and is commercially identified by the formula CO3.HO.Ni, reflecting its mixed carbonate-hydroxide composition.

In catalyst manufacturing, basic nickel carbonate serves as a precursor to nickel oxide and reduced nickel catalysts used in hydrogenation reactions, decomposing cleanly under heat to yield active nickel species without halide contamination. It is also processed within the mining and metals sector as an intermediate in nickel refining and in the production of nickel-based stabilisers for certain polymer systems.

This material is supplied as a green powder and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm supplier compliance documentation, including Safety Data Sheets aligned with EU CLP regulation, and specify technical or reagent grade depending on the intended catalytic or metallurgical application.
