| Abstract: | Liquid-phase sintering of MgO-5 wt% Bi2O3 was studied by loading dilatometry. The ratio of the creep viscosity to the densification viscosity (～1.8) and the sintering stress remained nearly constant in a wide density interval. These results, together with results on several other systems, indicate that the constancy of the sintering stress during densification may be a general phenomenon, regardless of densification mechanism. |
