Etchant according to Le CHATELIER

Le CHATELIER microetching agent is specially designed for use in metallography and scientific laboratories. Its use is mainly in the optimization of microstructures, especially for pure iron, carbon steels, low alloy steels and gray cast iron. Somewhat unusually, but nevertheless worth emphasizing, it is also applied to tin-coated steels and cast irons.

The detailed composition includes various chemicals. Among them are ethanol (C2H5OH), water (H2O), copper(I) chloride (CuCl), picric acid (C6H3N3O7) and fuming hydrochloric acid (HCl). This combination of chemicals promotes the efficient performance of etching.

The chemical interaction of these substances enables the elaboration of the microstructures. Ethanol serves as a solvent, cupric chloride and picric acid as oxidizing agents, and fuming hydrochloric acid promotes the solubility of the oxidizing agents. The velvety microstructural patterns that result after etching are the result of the chemical reactions of these substances with the metal.
