Nickel: Nickel to element 28 of the periodic table. It is a hard metal - malleable - shiny with crystalline and cubic structure, white and silver color. This element is the fifth most common element on earth. And is widely formed in the Earth's crust and core.
Application The per capita consumption of nickel in the world in various applications is as follows. 70% Made of stainless steels, 9% Made of non-ferrous alloys, 8% in plating. 9. Steel alloys and castings, 3. Battery making and 1. Other uses.
Specifications This element is a metal with atomic number 28 and the scientific symbol Ni in group VII. And in the fourth period there is a periodic table. Atomic mass 58.71, capacities 2 and 4. It has five stable isotopes.
Properties This alloy is a metal with extraordinary chemical and physical properties. Which has caused its use in hundreds of thousands of different applications. This element has a high melting point (1453 degrees Celsius), is very resistant to corrosion and oxidation. It is very malleable and easily combined with other alloying elements. It becomes. It is magnetic at room temperature and can be easily used in metal plating. This metal also has catalytic properties and can be 100% recycled.
The most common state of nickel oxidation is +2. Nickel +3 and +1 are also rarely found.
In terms of magnetic properties and chemical activity, it is similar to iron and cobalt. The main minerals of this element are pentlandite-pyrrhotite (nickel and iron sulfides) and garnierite (nickel silicon and magnesium). This element is one of the main constituents of meteorites. Iron and siderite meteorites, including iron alloys, contain about 5 to 20 percent of this element. Commercial nickel is in the form of pentlandite and pyrrhotite. These mines are found in the province of Ontario, Canada. This area supplies about 30% of the world's total nickel. Other mines of this element are in Australia - Cappadocia - Cuba - Indonesia and in other regions.
