Second, the system is heated to higher temperatures while compressing under moderate pressure levels (e.g. 500 MPa). The solubility of the powder is further increased and together with the evaporation of a liquid phase, the formation of supersaturated liquid is ensured. At this stage the applied pressure, as in the case for pressure-assisted conventional sintering,promotes densification. It is proposed that the latter stage is dominated by dissolution-precipitation events assisted by pressure and temperature [201].
