Nickel: smelting, producing-Metalpedia

It then decomposes, depositing pure nickel onto the nickel spheres. Alternatively, the nickel carbonyl may be decomposed in a smaller chamber at 230 °C to create a fine nickel powder. The resultant carbon monoxide is re-circulated and reused through the process. The highly pure nickel produced by this process is known as "carbonyl nickel".

Nickel Refining

The nickel sulfide is roasted to form nickel oxides, which can be further processed to nickel and nickel alloys. 15.4.2 Flow Stress, Cold Work, and Annealing Figure 15.6 displays a flow curve for nickel wire. 192 Using the relationship σ 0 = k ɛ 0 N, the nickel curve in Figure 15.6 can be approximated by:

Raney® Nickel: A Life-Changing Catalyst

Raney nickel is a heterogeneous hydrogenation catalyst. It promotes the reaction of hydrogen with organic compounds (compounds that contain carbon), and, like all catalysts, is not consumed in the process. Heterogeneous catalysts, like Raney nickel, are insoluble and easily recovered after reaction, so they can be used again and again.
