Used as a high-purity source of iron in research and industrial applications, particularly in materials science for alloy development and metallurgical studies. Commonly employed in electrochemical experiments, such as electrodes in corrosion testing or molten salt electrolysis due to its uniform diameter and high purity. Also utilized in the synthesis of iron-based compounds and catalysts where trace impurities must be minimized. Suitable for use in vacuum or high-temperature environments, such as in furnaces for vapor generation or as a feedstock in crystal growth processes.
