Application

Chlorine gas has been used to generate chlorine atoms via photolysis for molecular halogen photochemical experiments.
It can be used:
  • As a reactant for the extraction of gold from an alluvial material via a pyrometallurgical process.
  • To synthesize carbide-derived carbons (CDC) from zirconium carbide.
