Alcoholic Nitric Acid 4 %
Alcoholic nitric acid 4 %, consisting of ethanol and nitric acid is used especially in metallography and scientific laboratories. It is particularly suitable for surface etching in metallography (Nital) of unalloyed and low-alloyed steels, heat-treatable steels, cast irons and similar materials. In addition, it is a commonly used etchant for abrasive burn testing and pearl tonguing.
The chemical composition of the product consists of ethanol (C2H5OH) and nitric acid (HNO3). Ethanol acts as a solvent, while nitric acid serves as a strong oxidizing agent and caustic. The combination of these two substances results in a highly effective solution for removing surface contaminants and revealing the microstructure of metallic materials.
The chemical properties of this alcohol-based nitric acid solution make it possible to selectively etch the surface of metals, facilitating the examination of the internal structure of materials. When applied, a significant change in the surface structure becomes visible, allowing conclusions to be drawn about the nature of the material under investigation.
As a result, the use of alcoholic nitric acid 4% in the above areas enables detailed analysis of metals and other materials by visualizing their microscopic structures and chemical properties.
