    Howdy laura, Others here can give more detail, but 'cracking' ammonia
    into nitrogen and hydrogen is done by some folks who refine (and
    cast?) precious metals. It helps to remove oxides from the molten
    alloy/metal. Electronics manufacturers sometimes use the nitrogen
    component to protect solder paste from oxidizing during reflow.
