Analytic expressions have been developed to determine the activation energy of sintering using the Master Sintering Curve methodology. The analytical equations lead to values of the activation energy within 1% of the true value, whether noise is present in the data or not. The analytic expressions can further be used to discriminate between alternative kinetic models and to determine the pre-exponential factor. The origin of the accuracy of the analytical expressions is also discussed.
