告诉你一篇文章，上面有： Heat capacity, thermal conductivity, and thermal expansion of barium titanate-based ceramics YI HE (1) ; Abstract Barium titanate (BaTiO3)-based ceramics have been used widely as dielectric layers in manufacturing multilayer ceramic capacitors (ML-CCs) in the electronics industry. In this study, the heat capacities of two different BaTiO3-based ceramic materials were determined as a function of temperature using differential scanning calorimetry (DSC). The densities of these materials were measured at room temperature using Archimedes' principle. Using these experimental values, the thermal diffusivity and thermal conductivity of each material were determined at room temperature with a hot disk sensor, which is a transient technique for rapid thermal conductivity measurement. Finally, the linear coefficients of thermal expansion of these materials were determined using thermomechanical analysis (TMA) from -50 to 250 °C. All these data are useful in modeling the stress and the reliability performance of these chip capacitors under various conditions. Journal Title Thermochimica acta , 2004, vol. 419, no1-2, pp. 135-141. 6.17*10-6(0~50度），11.29*10-6（150~200度） |
