Forming gas
Forming gas is a mixture of hydrogen (mole fraction varies) and nitrogen. It is sometimes called a "dissociated ammonia atmosphere" due to the reaction which generates it: 2 NH3 → 3H2+ N2 It can be also manufactured by thermal cracking of ammonia in an ammonia cracker or forming gas generator. Forming gas is also used to regenerate catalysts in glove boxes and as an atmosphere for annealing processes. It can be purchased at welding supply stores. It is sometimes used as a reducing agent for low and high-temperature soldering and brazing, to remove oxidation of the joint without the use of flux.
