Atmosphere sintering ScienceDirect

Jan 01, 2010 Argon is an inert gas that is used as a sintering atmosphere to prevent gas/solid reactions such as oxidation, nitriding or hydriding. Argon is completely inert, thus, although it can yield sintering atmospheres with low partial pressures of water vapor (dew point), it is extremely difficult and costly to reduce its oxygen partial pressure to below 10 ‒ 6 atm. Inert atmospheres have a
