Marble's solution (Marble Etcher, nicu, nife) 1 Lt

Marble's solution is an etching solution used in metallography. This solution is often used to study the microstructure of various metals and alloys. Marble's solution is used particularly effectively to clarify the microstructure of steel and iron alloys.

Marble's solution is generally a solution containing nitric acid (HNO3) and ethanol (alcohol). Nitric acid dissolves different phases on the metal surface at different rates, while alcohol acts as a solvent and controls the reaction. In this way, different phases and components on the steel surface become more evident.

Marble's solution is often used to examine the microstructure of steels. This solution can be used particularly effectively to highlight martensitic phases, grain boundaries and other microstructural details in steels. The concentration and application time of Marble's solution may vary depending on specific applications and should be carefully controlled for optimum results.
