Etching Caustic Soda 1% M/V 1 Lt
Etching caustic soda is an etching solution used in metallography. It is often used to study the microstructure of steel and iron alloys. Caustic soda, that is, sodium hydroxide (NaOH), dissolves the oxide layer on the metal surface and provides the metal with a cleaner surface.
Caustic soda is generally used as a solution. This solution consists of a mixture of sodium hydroxide and water. While caustic soda dissolves dirt and oxides on the steel surface, it provides the metal with a cleaner and brighter surface. This etching process is often used as a preparatory step to clean the surface of the metal and examine its microstructure.
