... Key steps during compaction and effect of compacting pressure on green density. Source: Ref 5 Density increases up to approximately 95% of theoretical can be obtained by repressing after sintering. The attainment of a high density by sintering at a high temperature and/or for a long period of...

... double press/double sinter method, that is, first pressing to a green density of approximately 6.65 g/cm 3 , followed by sintering below the liquid-phase-forming temperature (for example, at 1204 °C, or 2200 °F), then repressing and sintering above that temperature. Reen explains its superior performance...
