摘要

Process for calibrating the temperature measuring system of a high temperature reactor comprises preparing a calibrating plate with a first concentration of doping material having a layer with a second concentration of the doping material, determining the thickness of the layer, thermally treating the calibrating plate in the reactor at a theoretical temperature measured by the temperature measuring system, determining the thickness of the layer again, and determining the actual temperature in the reactor during heat treatment from the difference of the thicknesses of the layer between the change of thickness of the layer and the temperature during heat treatment.
