Applications
Hydrogen is used in petroleum refining, metal treating, chemical processing, and electronics manufacturing. It serves as a carrier gas in gas chromatography, is essential in ammonia synthesis and methanol production, and is used as a reducing atmosphere in heat treatment furnaces. In the semiconductor industry, hydrogen is used for epitaxial growth and annealing processes.
