Spray dried granules of 3Y-TZP zirconia were die pressed into disc-shaped samples and cold isostatic pressed at 250 MPa. Sintering was conducted using either one step sintering at 1500 oC or two-step sintering, with pre-sintering at 1200 oC and final sintering at 1500 oC. Heating rates of 2 and 10 oC/min were used.

Atmosphere sintering - ScienceDirect

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

The reduction is the result of the reaction between the furnace atmosphere and the oxygen in the oxide layer. A typical sintering furnace atmosphere will contain Hydrogen and/or Carbon Monoxide to react with the Oxygen on the surface of the metal particles. The reducing potential of the furnace atmosphere is typically measured using the dew point.
