An electroless nickel coating is a dense alloy of nickel and phosphorus. The amount of phosphorus codeposited can range from less than 2% to more than 12%, depending upon bath formulation, operating pH and bath age. The deposition process is auto-catalytic; i.e., once a primary layer of nickel has formed on the substrate, that layer and

Full-scale testing of the process has commenced at a A$3.5 million pilot plant at CSIRO in Perth. The process, developed by Sydney-based company Direct Nickel, could deliver a huge boost to the global …

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".

The sourcing and refining processes of nickel play a pivotal role in defining its effectiveness within batteries used for electric vehicles. Nickel, when refined and alloyed suitably, enhances the properties of the battery components by increasing their energy density. This superior energy density directly translates into improved performance ...

Although the nickel market has registered only modest growth lately due to unfavorable economic conditions, process equipment supplier Outotec noted that analysts expect an upturn in the future. Outotec, in fact, said it has constantly been developing new, sustainable, and economically viable nickel processing methods—and its nickel matte …

Naturally, nickel is found in the form of sulfides and lat-erites. Laterites occur in limonite (oxides) and saprolites (silicates). These ores can be processed by beneficiation, …

Around 68% of all nickel available from consumer products is recycled and begins a new life cycle (reference year 2010); another 15% enters the carbon steel loop.
