Abstract

PZT ceramics were rapidly sintered in a 2.45GHz microwave oven without no addition of lead to the atmosphere and afterwards the piezoelectric properties were investigated. The specimens were sintered between 1050 and 1130$^{\circ}C$ with the sintering time totaling less then 20 minutes, reducing processing times and costs from those of established methods. The relative dielectric constant, mechanical quality factor and electro-mechanical coupling factor of the PZT specimens at 1090$^{\circ}C$ were 1990, 80,0.53 respectively, which is comparable to conventionally sintered values.
