CASTNER Meaning and
Definition
-
Castner is a noun that primarily refers to a type of electrolytic cell used for producing sodium metal and chlorine gas through the electrolysis of sodium chloride. The Castner cell, named after the American chemist and inventor Hamilton Castner, is an industrial device employed in the chlor-alkali industry. It consists of a cylindrical iron vessel that contains molten sodium chloride electrolyte, which serves as the medium for the electrolysis process. The Castner cell is equipped with a cast iron cathode that attracts sodium ions and a graphite anode that attracts chloride ions. When an electric current is applied, sodium ions migrate toward the cathode, where they gain electrons and deposit as molten sodium metal. Simultaneously, chloride ions move toward the anode, eventually combining to form chlorine gas. This process, known as the Castner process, is essential for the large-scale production of sodium metal and chlorine gas, important industrial substances used in various applications, such as the manufacturing of soaps, detergents, and PVC plastics. Furthermore, the Castner cell offers superior energy efficiency and has significantly contributed to advancements in the chlor-alkali industry.
