CAS 7439-93-2: Nickel
Introduction
Nickel is a silvery-white metal that is found naturally in the earth's crust. It is a hard and ductile metal that is resistant to corrosion and oxidation. Nickel is found in many forms, and is used in a variety of industries, including electroplating, metal production, and chemical processing. CAS 7439-93-2, or nickel, is the chemical name for the element nickel.
Properties
Nickel is a transition metal, with an atomic number of 28 and an atomic weight of 58.69. It has a melting point of 1453°C and a boiling point of 2913°C, and is found in the fourth period of the periodic table. Nickel is a silvery-white metal that is resistant to corrosion and oxidation, and has a relatively high electrical and thermal conductivity. It is also magnetic and has a relatively high density.
Uses
Nickel is used in a variety of industries, including electroplating, metal production, and chemical processing. Nickel is used in the production of coins, jewelry, and other decorative items. It is also used as an alloying agent in the production of steel and other metals. Nickel is also used in the production of batteries and catalysts, as well as in the production of chemicals. It is also used in the production of catalysts for petroleum refining.
Safety
Nickel can be toxic if inhaled or ingested in large quantities, and can cause skin irritation if it comes into contact with the skin. It is important to use proper safety equipment when working with nickel, such as gloves, masks, and protective clothing. When disposing of nickel, it is important to follow proper safety procedures, as it can be hazardous if it is not handled properly.
