Master sintering curves ( MSC s) were constructed for tape cast NiO, YSZ and NiO/ YSZ composite materials using apparent activation energies obtained through dilatometry experiments. A rule of mixtures approach was demonstrated to be a useful analysis tool in understanding the activation energy of the NiO/ YSZ composites since NiO and YSZ do not affect the sintering of the other phase. Prediction of the 48 vol% NiO composite was less accurate because of competing sintering modes near the percolation threshold.
