Simulation experiments make sure that the dilatometer is able to detect the expansion changes in low temperature. The high temperature reheating process with dilatometer analysis indicate that the firing temperature are little higher than 900℃ for one sample and lower than 900℃ for other five samples with firing temperature ranges of 550~650℃, 650~750℃ and 750~900℃. The results from mineral composition analysis of the samples by X-ray diffraction provide further evidence of the reliability of the thermal expansion measurement.
