Abstract
The internal temperature profile of the dielectric materials BaO-TiO2-Nd2O3 system for the ceramics calcination process has been measured using a thermocouple.The profile obtained differs from other dielectric materials basedon barium titanate.
At a low temperature range (-600°C), the rate at which the temperatureof the test dielectric material rises is low. Conversely, at a high temperaturerange (900-1200°C), the rate increases rapidly.
In order to clarify the mechanism of these phenomena, the reaction processof this system has been tested using TG, DTA, and X-ray diffraction methods.The results show that these phenomena are related to various transformationsof Nd2O3 with endo-or exothermic reactions.
