A silver-white transition metal with a glossy right is one of the elements with strong ferromagnetism at room temperature (the other two elements are iron and cobalt). In the entire temperature range below the melting point, the crystal structure of nickel is face centered cubic (fcc), and the lattice constant at 20°C is 0.35167 nm. Its melting point and boiling point are 1453°C and about 2730°C, respectively.
The relative atomic mass of pure nickel is 58.6934, the density of pure nickel is 8.902g/cm3 at 25°C, and the density of liquid nickel at the melting point is 7. 9g/cm, which decreases linearly with increasing temperature, and the density at 7500K is 7 .Og/cm3.
Pure nickel is a versatile and extremely important metallic material. Because of its good strength and toughness, it is widely used in industry. In addition to forming valuable alloys with other metals, pure nickel is also used alone with its excellent characteristics. Corrosion-resistant structural materials and functional materials.
In fact, the pure nickel used for corrosion-resistant structural materials is a carbon-containing nickel-carbon alloy, and the commonly used grades are Ni200 and Ni201.
