Notes:
Master sintering curve (MSC), in which the sintered density is a unique function of the integralof a temperature function over time, is insensitive to the heating path. In this paper, the densification ofrutile TiO2 was continuously recorded at heating rates of 2 °C/min and 5 °C/min, respectively, bydilatometer. The MSC for rutile TiO2 was constructed for pressureless sintering using constant heatingrate date based on the combined-stage sintering model. The construction and application of the MSC weredescribed in detail for different thermal histories. The MSC can be used to predict and control thedensification, final density, and microstructure evolution during the whole sintering. The final density canbe predicted for an arbitrary temperature–time path. A good consistence exists between the predicted andexperimental densification curve, confirming that it is possible to accurately predict and control thesintering behavior of TiO2 from the initial to final stage of sintering using MSC
