    Nickel metal relative atomic mass: ; Approximately silvery-white, hard, malleable and ferromagnetic metallic element, it is highly polished and resistant to corrosion, and conducts electricity and heat. At room temperature, nickel forms a dense oxide film on the surface of moist air, which can not only prevent further oxidation, but also resist the corrosion of alkali and salt solutions.

    When dissolved in nitric acid, it is green. It is mainly used in alloys (such as nickel steel and nickel silver) and as a catalyst, which can be used to make currency, etc., and plating on other metals to prevent rust. Density:

    The density of nickel is.

    Nickel is a hard, malleable and ferromagnetic metal that is highly polished and resistant to corrosion. Nickel is an iron-loving element. The Earth's core is mainly composed of iron and nickel.

    In the earth's crust, ferromagnesian rocks contain more nickel than siliceous aluminous rocks, for example, peridotite contains 1000 times more nickel than granite, and gabbro contains 80 times more nickel than granite.

    Uses: 1. Mainly used for alloys (formulas) (such as nickel steel and nickel silver) and as catalysts (such as Lane nickel, especially as a catalyst for hydrogenation), which can be used to make currency, etc., and can be plated on other metals to prevent rust. It is mainly used to manufacture stainless steel and other corrosion-resistant base closed alloys, such as nickel steel, nickel-chromium steel and various cracked non-ferrous metal alloys, and copper-nickel alloys with high nickel content are not easy to corrode.

    2. It is used as a hydrogenation catalyst and used in ceramic products, special chemical vessels, electronic circuits, glass greening and nickel compound preparation, etc.

    3. Electrolytic nickel: Electrolytic nickel is nickel made by electrolysis, and the stainless steel and various alloy steels made from it are widely used in aircraft, tanks, ships, radars, missiles, spaceships and civil industries in machine manufacturing, ceramic pigments, permanent magnet materials, electronic remote control and other fields.

    4. Nickel and its alloys are often used as catalysts for hydrogenation reactions. Raennie nickel is a commonly used form of nickel catalyst, which is a porous nickel-aluminum alloy, but many times other catalysts are used, such as the related "Rainnie-type" catalyst.

    Nickel, ni. Physical characteristics: silvery-white metal, very hard, good machinability, good vacuum performance, excellent welding performance. Melting point 1455, density, linear expansion coefficient, thermal conductivity, specific heat.

    Resistivity. Chemical Properties: Valency 2 and 3.

    It is not very active at room temperature and is not easy to oxidize. When heated to 400 in air, the surface will oxidize, and to 800, a thin layer of NIO will be formed on the surface. Hydrogen annealing at 350 can be reduced.

    Resistant to strong alkali and soluble in nitric acid.

    or a mixture of nitric acid and sulfuric acid.
