Hexachloroethane is primarily used in the metallurgical industry as a degassing agent to remove air bubbles from molten aluminum and its alloys, improving the quality and strength of the final product. It is also employed in the production of smoke-generating devices, such as smoke grenades and pyrotechnics, due to its ability to create dense, white smoke when burned. In addition, it has been utilized as a component in certain fungicides and insecticides for agricultural purposes. However, its use is increasingly restricted due to environmental and health concerns, leading to the exploration of safer alternatives.
