In this study, we investigate the experimental conditions influencing the reproducibility of temperature measurements such as the temperature control location and the die asymmetric location relatively to the sample. In this context, we used a finite element modeling (FEM) and a series of experiments under temperature control mode to check the repeatability of the temperature measurements during SPS sintering and also allows to evaluate the robustness of the present model. An alumina sample was studied as an electrically insulator ceramic material. A thermal sintering cycle is imposed using a control pyrometer of temperature on the top graphite punch near the sample.
