Abstract
A method for lowering the oxygen potential of an inert processing atmosphere containing a reducing gas such as hydrogen, by introducing a metal catalyst to induce reaction between the reducing gas and oxygen, which may originate from leaks into the system or from other sources. The catalyst, such as a precious metal, increases the rate of reaction between gaseous hydrogen and gaseous oxygen to form water vapor, thereby decreasing the amount of molecular oxygen available to react with oxidizable materials exposed to the inert processing atmosphere.
