Picric acid solution, alcoholic

Picric acid solution, alcoholic is a ready-to-use solution for use in metallography and scientific laboratories. It consists of picric acid, distilled water, denatured ethanol and isopropanol.

In metallography, the picric acid solution is used as a modified etchant for pure iron, carbon steels, low-alloy steels and gray cast iron. The solution contributes to microstructure development and enables detailed analysis of metallic samples. The chemical properties of picric acid and the alcohols it contains, especially isopropanol, enhance the etching properties of the solution.

The application of picric acid solution in metallography results in visible disclosure of the microstructure of the materials under study, which is important for the study of the structural properties and quality of the materials.

Possible results of the application of this solution include significant microstructural development in metallic samples, which contributes to improved analysis and interpretation of the material structure.
