Nickel Equipment

A dense oxide film is formed on the surface of the moist air at room temperature, which can prevent the bulk metal from continuing to oxidize. Hydrochloric acid, sulfuric acid, organic acid and alkaline solution of nickel erosion is very slow. Slow dissolution of nickel in dilute nitric acid. Strong nitric acid can make the surface passivation and corrosion resistance. Like platinum and palladium, nickel can absorb a large amount of hydrogen, the smaller the particle size, the greater the amount of absorption. The important salts of nickel are nickel sulfate and nickel chloride. With iron, cobalt is similar, at room temperature for water and air are more stable, can resist alkaline corrosion, so the laboratory can be used in Nickel Crucible Melting alkaline material. Nickel is soluble in dilute acid, and iron is different from that of cobalt and nickel with intense reaction, and the reaction is slower with dilute nitric acid.
