Sintered body of lead zirconate titanate (PZT) was prepared through the spark plasma sintering (SPS) technique. When the mixture of raw materials was calcined at 800 deg C and sintered at 900 deg C for 10 min. with SPS technique, the sintered body had almost theoretical density but was a mixture of lead titanate (PT) and PZT. When a calcining temperature of 1100 deg C was employed, sintered body had a single PZT phase but a lower density. High dielectric constant was obtained for a sample calcined at 800 deg C, sintered with SPS technique and fired again in the air at 1100 deg C.
