Abstract

Fabrication of piezoelectric functionally gradient material by temperature gradient sintering is described. The temperature gradient was given by an infrared-rays lamp beam and a controlled auxiliary heater. Cylindrical PZT powder compacts were air-sintered lhr with a temperature difference of about 150K in the distance of 5mm from the sample surface. The variation of relative density along the axial direction was found to be well corresponding to the local temperature gradient within the sample. It was found that a flexural vibration mode was generated due to the density gradient along the axial direction.
