A Master Sintering Curve (MSC) for rutile TiO2 was constructed for Pressure-less sintering using constant heating rate dilatometry data based on the combined-stage sintering model. Construction of the master sintering curve is described and the validation is proved with rutile TiO2 under different thermal histories. The concept of master sintering can be used to predict the sintering shrinkage and final density and calculate the activation energy, and a value of 105 KJ/mol for TiO2 was obtained. With one temperature dependent parameter determined experimentally, it became possible to describe accurately the densification behavior of TiO2 from the initial to final stages of sintering.
