Abstract:
Young’s modulus and thermal diffusivity values have been obtained on a set of barium titanate based ceramics using ultrasonic pulseecho and photoacoustic effect (PAE) measurements. The PAE was shown to detect variations in thermal diffusivity between materials of varying composition and processing treatments. The results are valuable in the evaluation of dielectric ceramic materials for practical electronics applications.
