Physical Properties of Electrodeposited Nickel

nickel electrodeposits has been studied (Chart, 1977). Nickel sulfamate deposits with tensile internal stress were obtained from conventional solutions; the stress was stable at 50MPa (7,252 psi). (The solution contained 70 g/l of nickel metal as the sulfamate, 0.1 g/l of chloride added as nickel chloride hexahydrate, and 35 g/l boric acid. The pH was 4.0, temperature 60 C, and cathode current ...

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Nickel - Simple English Wikipedia, the free .

Nickel was found when a copper-coloured ore did not make copper metal. Later it was found out that the ore was actually a nickel containing ore. Nickel was isolated as a metal in 1751. At first, the copper colored nickel ore was the only source. Later, it was made as a byproduct of cobalt blue making. Preparation
